Normally Closed Air Switch AS-2

AS-2 Normally Closed Commercial Garage Door Air Switch

Ensure reliable safety performance with the AS-2 Air Switch, a key component of commercial garage door sensing edge systems. This air switch is factory-set in the normally closed position and designed to enhance protection for commercial door operators.

How It Works

The AS-2 connects to a pressurized air chamber inside the bottom seal of the door. If the chamber meets an obstruction, the displaced air triggers the switch. Once activated, the switch sends a signal to the operator to stop or reverse the door, helping prevent damage and improve safety.
