Lennox 30H65 Interlock Switch W/Wire Lead

The Lennox 30H65 Interlock Switch With Wire Lead is an interlock switch that is installed in different HVAC appliances. It works like a (SPST) switch; it has one pair of contacts that are open and close when there is a door in one position. When the door is closed, the switch then makes the circuit and allows the flow of electrical current. On the other hand, when the door is opened , this switch is released, thus breaking the circuit. A safety measure within the HVAC system that doesn’t allow the equipment to run with the door opened to avoid harm or incidental damage.
