The G503-AT is a heavy-duty foot switch for tough industrial, factory, and shop applications. Includes oversized guard, rugged housing, and precision Honeywell switches. This foot switch has an anti-trip pedal action, meaning the user must press forward a latch inside the hood before pressing down on the pedal to turn it on, which provides an additional measure of safety by reducing accidental activation. These units then have a momentary action; the user must keep the pedal pressed down in order to keep it on.
