Seal. Secure. Operate.
The AS-1 3-Wire Air Switch is a key component in non-monitored reversing safety edge systems used in commercial garage door operators. Designed for both interior and exterior use, this versatile air switch is compatible with 2- or 3-wire operator setups and helps enhance the safety and reliability of overhead door systems.
This unit operates by connecting to a pressurized air chamber within the bottom seal of the door. When an obstruction is detected and compresses the chamber, air pressure activates the switch, which sends a signal to the door operator to stop or reverse movement—helping prevent damage and injury.
The AS-1 model features convertible contact settings, allowing users to configure it as either normally open (NO) or normally closed (NC), depending on their system’s requirements. It's ideal for installers and technicians working on commercial doors, loading docks, and industrial access points.
