These stabilizers are to be used with Kailh Choc V1 switches only. They will not work with Cherry MX switches! The are intended to stabilize keycaps 2u and larger on a low profile keyboard.
These stabilizers get mounted between the PCB and the switch plate of a keyboard, each of which having special cutouts to accept them. A switch plate is absolutely required to utilize these stabilizers! This style of stabilizer will not stay in place if either the PCB or the plate is missing.
This kit consists of 6 complete stabilizers:
1 x 6.25u spacebar stabilizer (cross mounts 100mm on centre)
5 x 2u modifier stabilizer (cross mounts 25mm on centre)
Made by Kailh, with installation instructions included.
