A convenient alternative to a wall switch, the stylish SinkTop Switch from InSinkErator is air-activated and easily mounts to the sink or counter top. It is also ideal for island installations. The SinkTop Switch is for use with all disposers (must have AC power below sink.)
I have an Insinkerator model Z1456 Air switch for my garbage disposal and the switch broke, do you see a replacement without having to buy the whole kit? See photo
