The Honeywell 120V SPST Switching Relay is a high-performance electrical component designed for the precise control of line-voltage equipment in HVAC and hydronic heating systems. This single-pole single-throw (SPST) relay acts as a reliable interface, allowing a low-voltage thermostat or controller to manage high-voltage electrical loads safely and efficiently. Commonly used to operate circulator pumps, boiler controls, and fan motors, this switching relay ensures smooth system operation and consistent temperature regulation. Built with professional-grade materials, it is an essential replacement part for maintaining residential or light commercial heating installations and ensuring long-term system reliability.
Type: Electrical Switching Relay
Size: Compact
Application: Ideal for hydronic heating systems, circulator pump control, boiler electrical circuits, and general-purpose switching of line-voltage loads from a low-voltage signal.
Specifications: Input Voltage: 120V AC; Contact Arrangement: Single Pole Single Throw (SPST); Function: Low-voltage to high-voltage switching; Compatibility: Works with 24V thermostats and controllers.
