Many outdoor AC units have a shutoff switch. These switches are typically located near the unit and are within a metal box mounted to the exterior of your home. They are sometimes labeled as an emergency shutoff.

Then, What is a safety switch on an air conditioner?

The reason is simple: there is a safety switch in the drain pan that, when water fills the drain pan, the switch prevents all, or some of the air conditioning system turning on. This in turn stops the AC system from evaporating the moisture from the air so that no more water is produced.

Considering this, Why does my AC drain keeps clogging? As the air conditioning unit cycles the air and bring the temperature down it removes the humidity from the air. This humidity is sent to your drain line that might end somewhere outside in your property. The drain pipes may get clogged with dust, sludge or biological growth.
