Whether a keyboard can accept magnetic switches is not simply a matter of swapping parts. The PCB, sensor hardware and firmware must be designed to read them. This guide explains the compatibility rules, switch selection and model-specific limits that determine whether Hall effect switches are suitable, including the purpose-built Hall Effect keyboards available from Krome Keyboards.
Do magnetic switches work on any keyboard?
Magnetic switches do not work on just any keyboard: no. A Hall effect switch requires a keyboard built around magnetic sensing from the circuit board upwards. Although its shape may resemble a standard MX-style switch, that physical similarity does not create electrical or logical compatibility with a conventional mechanical keyboard. Consult the magnetic switch compatibility guide from Krome Keyboards to check which switch models work with specific PCBs.
Why the sensing systems differ
A conventional mechanical keyboard closes a metal-leaf circuit when a key bottoms out, sending the controller a binary on/off signal. By contrast, a Hall effect switch carries a magnet whose changing position alters the magnetic field measured by a Hall sensor in the PCB. The sensor produces a continuous analogue voltage rather than a simple open-or-closed signal.
That difference determines compatibility. The PCB must be able to read analogue output, which standard boards are not equipped to do.
- Binary versus analogue: A standard mechanical keyboard PCB detects contact closure, while a Hall Effect PCB reads a continuously varying voltage from the magnetic sensor. The two switch types require different hardware.
- Integrated Hall sensors: Compatible boards have Hall sensors physically built into the PCB at each switch position. Conventional mechanical designs lack these sensors, and they cannot be retrofitted.
- Dedicated firmware: Purpose-built Hall Effect keyboards use firmware that interprets analogue magnetic data in real time. Standard mechanical firmware is designed for digital input and cannot process magnetic field changes.
- Calibration routines: Hall Effect keyboards include factory calibration routines that map sensor output to key position. A standard mechanical keyboard has no equivalent calibration infrastructure.
As a result, moving from a mechanical keyboard to Hall Effect technology means buying a complete purpose-built keyboard rather than sourcing a batch of magnetic switches. Krome Keyboards’ range of Hall Effect keyboards with magnetic switches includes the AKKO MOD68 HE ISO and the SKYLOONG GK68HE Pro, both engineered with the required PCB architecture from the outset.
What a compatible keyboard needs
Compatibility depends on the hardware present in the board. A compatible keyboard integrates Hall sensors into its PCB, a controller capable of reading analogue signals and firmware that can respond to those readings continuously. Manufacturer specifications that explicitly mention Hall Effect or magnetic switch support provide the clearest starting point; adjustable actuation and Rapid Trigger features further indicate that the necessary hardware is present.
Those using Krome’s custom keyboard builder with magnetic switches can select pre-configured Hall Effect models alongside compatible switch options.
- Hall sensor array: The PCB must have Hall sensors at every switch position, integrated during manufacture to measure the magnetic field produced by each switch’s internal magnet.
- Analogue signal processing: The controller must read a continuous voltage range rather than a simple on/off state, requiring dedicated analogue-to-digital conversion hardware on the board.
- Matching firmware: The operating firmware must support real-time analogue input, adjustable actuation point configuration and, where relevant, Rapid Trigger functionality.
Some newer hybrid models support both switch types through dual-compatible PCBs, although these remain rare in the current market. For most users, a purpose-built Hall Effect keyboard is a reliable choice because its sensor, controller and firmware are unified and validated by the manufacturer, reducing the risk of incompatible hardware combinations.
Krome’s Hall Effect range is limited to dedicated models. The AKKO MOD68 HE ISO uses the MOD68 HE PCB in an ISO 65% layout with CNC aluminium gasket-mount construction, while the SKYLOONG GK68HE Pro uses the GK68 HE PCB in ANSI format with a plateless mount. Each keyboard’s specification explicitly identifies Hall Effect as its switch type, providing the clearest indication of genuine switch compatibility.
How a magnetic switch keyboard works
Understanding how a magnetic switch keyboard works explains why this technology cannot simply be added to an ordinary board. The sensing chain—magnet, sensor, controller and firmware—must operate as one integrated system.
Magnetic sensing instead of contacts
A conventional switch completes a circuit when two metal leaves touch. By contrast, a Hall Effect switch contains a small magnet inside its housing. As the key descends, the magnet moves towards a Hall sensor on the PCB, which measures the resulting change in magnetic field strength.
This continuous reading replaces binary contact closure. A keyboard with magnetic switches therefore produces positional data for each key instead of a simple pressed-or-released signal, making analogue features possible. The Hall Effect switches work without physical contact between their moving parts and the circuit board, so the switch design avoids contact degradation that can affect mechanical alternatives over time.
Akko's AstroAim and TTC's Flip King Magnetic switches are factory-lubricated and include customisable pre-travel settings. Their contactless operation contributes to a smoother keystroke from the first press.
Adjustable actuation and Rapid Trigger
This adjustable actuation lets the user set the actuation point in software rather than relying on a fixed physical threshold.
Krome's hall effect keyboards expose this setting through manufacturer software or a web configurator, with preferences saved to onboard memory for use across systems. Rapid Trigger extends the same principle: a key can reset and register again according to movement rather than a fixed return point.
A key can re-activate within fractions of a millimetre of upward travel. That behaviour is particularly relevant to fast counter-strafing and repeated inputs in competitive gaming. Both the AKKO MOD68 HE ISO and SKYLOONG GK68HE Pro support Rapid Trigger and operate at an 8K polling rate to keep latency minimal.
Advanced settings—including the actuation point, Rapid Trigger sensitivity and per-key configuration—require the manufacturer's software or web configurator. The software-defined approach delivers advantages over conventional switch types by moving customisation from physical hardware to firmware parameters.
Calibration and response limits
Hall Effect sensors are sensitive to temperature variation, so readings can drift slightly during shipping or extended use in changing environments. Running the manufacturer's calibration function after receiving a new keyboard corrects that drift.
Both AKKO and SKYLOONG provide software tools for this routine. Repeating calibration periodically makes sense when a keyboard moves between significantly different ambient conditions.
Rapid Trigger resolution depends on the keyboard's IC hardware and sampling rate, not solely on the switches installed. A keyboard capable of 0.1 mm resolution remains limited to that figure regardless of the switch model fitted; a switch rated for finer sensitivity cannot raise the keyboard's hardware limit.
The AKKO MOD68 HE ISO and SKYLOONG GK68HE Pro both operate at an 8K polling rate, which sets the practical ceiling for response precision on those models.
Checking Hall Effect switch compatibility
Magnet polarity, physical dimensions, pin configuration and the manufacturer's approved switch list all determine whether a switch will work with a particular Hall Effect PCB.
Match the PCB and magnet polarity
Magnet polarity is a frequently overlooked factor in hall effect switches compatibility. The pole facing down towards the PCB sensor determines how the keyboard firmware interprets the magnetic field. Magnetic switches cannot be fitted to every keyboard without checking this orientation first: an N-pole-down switch installed in a board calibrated for S-pole-down operation will not register correctly, even when its physical dimensions match.
- S-pole down required Akko MOD68 HE keyboards are calibrated for switches with a downward-facing S-pole magnet. An N-pole-down switch such as the Astrolink will therefore produce incorrect readings.
- N-pole-down switches Akko Astrolink magnetic switches use a downward-facing N-pole magnet, so they are incompatible with keyboards that require the S-pole orientation, despite looking identical to compatible models.
- Sensor calibration alignment Magnet strength also interacts with the keyboard's sensor calibration. Even with the correct polarity, a switch with substantially different magnetic characteristics may fall outside the calibrated range of a particular PCB.
Krome's Hall Effect switch range includes Akko AstroAim, Astrolink and Flash models, Skyloong Crystal Blue Magnetic, TTC Lite KOM HE Magneto and TTC Flip King Magnetic. Each carries model-specific compatibility designations for particular keyboard PCBs, including "Akko MOD68 HE Compatible Switches" and "Skyloong GK68 HE Compatible Switches".

Confirm physical fit and mounting
Physical compatibility still requires separate verification of the switch dimensions and housing shape against the keyboard's plate cut-outs and case clearances. The SKYLOONG GK68HE Pro uses a plateless mounting style, which changes how the housing is supported. By contrast, the AKKO MOD68 HE ISO uses a plate with gasket mounting, so both plate compatibility and housing dimensions affect whether a replacement switch seats correctly.
Some magnetic switches have two-pin legs that engage with matching sockets on the PCB; if those sockets are absent, the pins require trimming before installation. That physical modification only addresses mechanical seating and cannot solve electrical or sensor incompatibility. A PCB without pin sockets should therefore prompt a complete compatibility check rather than an immediate physical workaround.
Use model-specific compatibility lists
Krome Keyboards organises its listings of Hall Effect switches around specific keyboard models. Products are labelled "Akko MOD68 HE Compatible Switches" or "Skyloong GK68 HE Compatible Switches" because compatibility does not transfer automatically across all keyboards with Hall Effect technology. Across Krome's Hall Effect switch range, actuation force starts at 25 gf on the Akko Flash and reaches a maximum end force of 55 gf on the Akko AstroAim, while total travel ranges from 3.4 mm to 3.5 mm. These specifications affect both typing feel and sensor calibration on a given PCB.
The lists maintained for each PCB model, MOD68 HE and GK68 HE, bring those details together and provide the most efficient starting point for selecting replacement or upgrade switches for a Krome Hall Effect keyboard. They also cover switch stem specifications and board mounting requirements.
Hall Effect switches versus a mechanical keyboard
Choosing between a Hall Effect keyboard and a standard mechanical keyboard involves more than sensing technology. The difference comes down to the wider customisation model: mechanical keyboards concentrate options in physical hardware, while Hall Effect keyboards move more control into software and firmware. That distinction helps match each keyboard to practical priorities, including competitive gaming, typing feel and long-term modding flexibility.
Are magnetic switches hot-swappable?
Magnetic keyboard switches are not hot-swappable in the broad sense supported by many mechanical keyboards. A hot-swappable mechanical keyboard can accept and remove compatible contact-based switches with relatively little restriction. Hall Effect keyboards are more selective: replacement must respect polarity, sensor calibration and the manufacturer’s approved switch list for the relevant keyboard switch position on the PCB.
- Mechanical hot-swap: Many mechanical keyboards use socketed PCBs that accept compatible MX-footprint switches. This provides broad physical modding flexibility, with checks usually limited to details such as pin count.
- Hall Effect replacement: Replacing switches in a Hall Effect keyboard requires polarity verification, calibration-range matching and confirmation against the manufacturer’s model-specific compatibility list before installation.
- Software customisation: Magnetic keyboards offer per-key actuation adjustment and Rapid Trigger configuration through software. A hot-swappable mechanical keyboard cannot reproduce those functions through physical switch changes alone.
- Firmware dependency: Hall Effect keyboards require the manufacturer’s firmware and software ecosystem for advanced features. Standard mechanical keyboards often support open or community firmware, which can broaden physical modding options across different models.
By contrast, mechanical keyboards with hot-swap sockets allow wider cross-brand switch experimentation and may support community firmware beyond the manufacturer’s tools.
Benefits and trade-offs
The main advantages of Hall Effect technology are fast magnetic sensing, an adjustable actuation point and dynamic Rapid Trigger on compatible hardware. A standard mechanical keyboard cannot provide variable actuation without a physical switch change, nor can it create dynamic Rapid Trigger. Against those benefits, Hall Effect keyboards require the manufacturer’s software for full functionality, need periodic calibration and offer more restricted switch compatibility than a standard mechanical keyboard with open hot-swap sockets.
Keycaps and keyboard customisation
Keycap compatibility on Hall Effect keyboards is more straightforward than switch compatibility. Current Hall Effect switches, including all models in Krome’s range, use MX-compatible stems, so standard Cherry MX-mount keycaps fit without requiring a dedicated keycap standard. As a result, keycap selection for a Hall Effect keyboard is broadly comparable to that of a standard mechanical keyboard: profile, colourway and language layout remain independent of the underlying switch technology.
Krome’s Keyboard Builder supports complete keycap configuration alongside Hall Effect keyboard and switch selection. Available PBT keycap profiles include OEM, a sculpted shape suited to everyday typing; Cherry, which provides a lower profile for a refined typing feel; and XDA, a uniform-height profile with a minimalist appearance. Layout options cover UK, German, French and Arabic, while keycap choice remains separate from the switch-to-PCB compatibility requirements outlined above.
Frequently asked questions
Can Hall Effect switches be installed in a standard mechanical keyboard?
No. Hall Effect switches require a keyboard designed around magnetic sensing hardware. A standard mechanical keyboard PCB detects electrical contact closure, so it lacks the Hall sensors, analogue signal-processing circuit and compatible firmware that a Hall Effect switch needs. The practical upgrade path is a purpose-built Hall Effect keyboard, such as the AKKO MOD68 HE ISO or SKYLOONG GK68HE Pro available through Krome Keyboards, rather than a switch-only conversion of an existing board.
Are all Hall Effect switches compatible with each other's keyboards?
No. Hall Effect switches are not universally interchangeable between Hall Effect keyboards. Magnet polarity is critical: the Akko Astrolink has a downward-facing N-pole magnet and is incompatible with a keyboard calibrated for an S-pole-down orientation. Magnet strength, sensor calibration range, physical dimensions, mounting style and pin configuration also affect compatibility. Krome Keyboards identifies the compatible keyboard model in its switch listings, including MOD68 HE and GK68 HE, so the correct match can be checked before purchase.
What features does a Hall Effect keyboard offer that a mechanical keyboard cannot?
A Hall Effect keyboard allows adjustable actuation, so each key can be set to register at a chosen travel distance. That setting cannot be changed on a standard mechanical keyboard without physically replacing the switch. Hall Effect keyboards also support Rapid Trigger, which resets and reactivates a key according to movement distance rather than a fixed return point, enabling faster repeated inputs. The AKKO MOD68 HE ISO and SKYLOONG GK68HE Pro from Krome support these features at an 8K polling rate, with settings configured through manufacturer software and saved to onboard memory.
