I am renovating my house. The contractor has rewired my house and installed rocker switches for my lighting. The big button looks good. But flipping the switch produces a loud snapping sound. Short of replacing those switches, is there a way to soften the audible click whenever I flip the wall switch?
Is it mounted on wood or plywood surface?
The loud snapping sound probably due to the the vibration amplification by the surface on which the rocker switch is mounted on.
The very first thing you could do is try install a layer of felt or similar soft material between the contact surfaces of the switch and the wall on which its mounted on.
This should reduce the sound significantly. If its still loud for you, go one step further to disassemble the switch and stuff the moving nonconductive parts with damping grease.
Here you can find about the grease I am talking about.
