North Shore Commercial Door Knows how important it is to stick to a budget when doing repairs. That being said, we have everything you could ever dream of to improve or repair your garage doors at a reasonable cost! Whether you need residential or commercial doors, we have pieces and parts for everything. For example, we have three different types of air switch models, A normally open, normally closed, and normally open or closed.

The AS-3 is part of a safety precaution called sensing edge kit for commercial operators. In order to function the air switch connects to a pressurized air chamber which sits within the bottom seal of the door. If the air chamber meets an obstruction, the displaced air activates the air switch. The switch then sends a signal to the operator which then reverses or stops the movement of the door.

This particular Air switch’s contacts are set in the normally open position. It is important to know that Sensing Edge Systems are non-monitored, meaning that it is up to the consumer to inspect the safety feature and make sure it is up to UL standards.
