How to Use a Wall Switch for a Garbage Disposal

Wire your garbage disposal to turn on with a convenient flick of a switch. This can be done by installing a new switch or converting an existing electrical outlet into a switch to turn the disposal unit on and off. A garbage disposal unit can be wired once it has been installed and secured to the sink and plumbing.
