HVAC Safety Component
Combustion Air Differential Safety Switch
This differential air pressure switch senses pressure changes across the boiler combustion chamber or fan assembly. When sufficient draft is confirmed, the internal diaphragm trips the SPDT microswitch to signal the main control board to proceed with burner ignition.
