Works fine but buzzes when driving LEDs at mid to high brightness
I bought this to replace an LED dimmer from a well-known brand with a sticking on/off switch. It fitted the old front panel easily. It also seemed to dim the LEDs okay, but unfortunately made an easily audible buzzing noise from mid to high brightness. This is a real shame as the push on/off action is much softer than that on the old switch, so I was optimistic about its lifetime.

dimmer mounting
I have a twin dimmer swtichplate on which one of the dimmer units could no longer be firmly held to the cover plate. The dimmer was fine but the mounting not so. This fixed that without undue issue and works properly.
