Commercial garage door Air Switch for pneumatic reversing safety edge kits on commercial doors. The 3-wire Air Switch connects to a pressurized hose attached to the doors bottom seal. If the air chamber meets an obstruction, the displaced air activates the air switch. The Air Switch then sends a signal to the operator to reverse or stop movement of the door. This switch can set the contacts in either normally open or normally closed positions. Sensing edge systems are non-monitored, meaning it is up to the consumer to inspect the safety feature and ensure it meets UL standards. Works with treadle hose, gum hose, and coil cords for increased safety on commercial garage doors.
