This diagram locates published travel points on a common 0–4 mm axis. It is not a force–travel trace and does not reconstruct tactile peak, return force or bottom-out force.
Before-you-buy note
The Properties table publishes 45 cN actuation force. CHERRY offers variants with and without PCB mounting pins; verify the exact article number.
A useful personal conclusion requires the exact keyboard, plate or integrated structure, mounting, keycaps, modification state, sample count and procedure. Begin with a small sample; do not turn a matching number into a universal sound, comfort or compatibility claim.
