The G503-MA is a heavy-duty foot switch for tough industrial, factory, and shop applications. Includes oversized guard, rugged housing, and precise Honeywell switches. This foot switch has a maintained action, which means you press down on the pedal to turn it on, and the unit will stay on until the user presses forward a latch inside the hood to release the pedal back to the “off” position. You can therefore remove your foot from the pedal and it will stay on (until the latch inside the hood is pressed forward to turn it off).
