Ttc Snow HE Linear Switches

The TTC Snow Magnetic HE is a linear mechanical switch designed for users seeking a smooth, consistent keypress with adjustable actuation. It uses magnetic sensors instead of physical contacts, reducing bounce and chatter. This switch suits enthusiasts interested in a unique magnetic actuation experience but requires compatible PCBs and is not suitable for standard mechanical keyboards.

Feel and Actuation

• Linear and smooth keypress without tactile bumps or clicks.
• Actuation is determined by distance traveled rather than a fixed point, allowing some adjustability in response.
• Light initial force of 32g offers a relatively easy press, with a total travel of 3.4mm.
• Magnetic sensing eliminates physical contact bounce, resulting in consistent input without chatter.

Build Quality

• Stem made of POM (polyoxymethylene) for low friction and durability.
• Top housing is clear polycarbonate, bottom housing is POM, both with ventilation holes to reduce heat and dust buildup.
• Includes an 18mm spring designed to complement the magnetic actuation system.

Compatibility and Limitations

• Plate mount design requires special PCBs compatible with magnetic or Hall Effect switches.
• Not compatible with standard mechanical keyboards or all magnetic switch systems due to manufacturing variations.
• Unknown compatibility with LED lighting or hot-swap sockets.

Trade-offs

• Requires specialized hardware, limiting use to certain custom builds.
• Adjustable actuation is based on travel distance, which may feel less precise compared to fixed points.
• Unknown factory lubrication quality and modification potential.
