⚡ Hall Effect magnetic switch corner
The hot new category: magnet + sensor instead of contacts → adjustable actuation (down to 0.1 mm) and rapid trigger. We track 7 HE switches — with board sockets and magnet polarity — and which boards accept them.

How to use this site
Pick a switch — filter by type or force, open a row for the spec sheet and stylized force curve.
Check compatibility — the checker judges switch × keycap profile × layout, including HE stems, low-profile mounts and row-kit needs.
A switch that measures stem position with a Hall Effect sensor and magnet instead of metal contacts, letting you set the actuation point anywhere in the travel and use rapid trigger. It only works on boards with Hall Effect PCBs.
Do all keycaps fit all mechanical switches?
Most keycap sets use the Cherry MX cross stem and fit standard switches, but low-profile (Choc) switches and some Hall Effect stems need specific caps. Sculpted profiles also need the right row kits for compact layouts.
Is my data uploaded anywhere?

Basis & sources
What this page rests on — and what it deliberately does not claim.
There is no official standard for keycap or switch compatibility. Figures here follow manufacturer datasheets and community measurements (mm, not inches); treat them as a starting point before buying — not a compatibility guarantee.
