Description
The Rheem-Ruud 42-105601-33 Pressure Switch is a control part that measures the air or refrigerant pressure and closes or opens its internal contacts when the set thresholds are exceeded. It is installed in the pressure line and is designed to be installed in gas furnaces, air handlers and packaged rooftop units to detect the differential pressure. The switch breaks the control circuit when the pressure is beyond the safe limits to avoid unsafe operation. This pressure switch use in proper sequencing of the system, safeguards system components against conditions, and is used to maintain constant performance in compatible HVAC equipment.
