Gateron Magnetic Spark HE Linear Switches

This linear switch uses magnetic sensing instead of physical contacts to register keypresses, resulting in a smooth and consistent typing experience without bounce or chatter. It suits users who want a quiet, fluid keypress with adjustable actuation distance. However, it requires compatible PCBs designed for magnetic or Hall Effect switches and is not compatible with standard mechanical keyboards.

Feel and Sound

• Linear and smooth keypress with no tactile bump or click.
• Magnetic sensing reduces noise from contact chatter, making it quieter than typical mechanical switches.
• Bottoming out feels consistent due to a 45 cN force, providing a solid but not harsh finish.

Actuation Characteristics

• Actuation point is adjustable based on travel distance, not fixed location, allowing customization of key response.
• Initial force is light at 33 cN, which supports fast and effortless keypresses.
• Total travel of 3.2 mm is standard, with a 22 mm spring length contributing to smooth compression.

Build Quality

• Polycarbonate stem and top housing provide durability and smooth stem movement.
• Bottom housing is made of nylon (PA66), offering structural stability.
• Lubed springs reduce spring noise and improve smoothness.
• Uniquely cylindrical stem shape may affect keycap compatibility or feel compared to standard MX stems.

Compatibility

• Requires special PCBs designed for magnetic or Hall Effect switches, limiting use to compatible keyboards.
• Not compatible with standard mechanical keyboard PCBs or hot-swap sockets.
• May not work with all magnetic or Hall Effect keyboards due to manufacturing variations.

Trade-offs

• Limited compatibility restricts use to specific keyboard builds.
• Adjustable actuation requires compatible firmware or hardware support, which may complicate setup.
• Unknown long-term durability beyond rated 100 million operations.
