This product only applies to PCB satellite switch, the switch plays a buffer role, while protecting the positioning plate friction.
Satellite switch buffer pads is divided into two materials, respectively, Teflon and transparent silicone material, after testing the Teflon sound will be more crisp, silicone sound will be more dull.
Transparent satellite switches can be easily lifted up and cause the steel wire to fall off, so it is recommended to use them in conjunction, improve overall stability.
