Silencer pad made from 3M foam material to maximize the sound dampening.  These are made specifically for Qanba's Gravity Mechanical pushbuttons in the 30mm size

Note:  When installing, leave the film on the back of the foam pad, otherwise it will be too sticky to apply and difficult to remove should you choose not to utilize it in the future.  For the easiest installation, we suggest removing the switch first, however, it is possible to install with the switch present
