Lochinvar & A.O. Smith 100108690 SPDT Pressure Switch -0.15" WC

The Lochinvar & A.O. Smith 100108690 SPDT Pressure Switch is an important component of HVAC systems that is used to measure pressure of gas and air in equipment. Working at -0.15”WC differential, this switch controls its contacts either to open or close depending on pressure variations and is used in the operation of appliances such as water heaters and boilers. This makes it reduce on cases of unsafe situations which in turn makes the system more safe and effective. As a result of the precise pressure regulation, the switch helps save energy and prolong the service life of equipment, which is invaluable for contemporary HVAC systems.
