Spence uses a color-coding system for their pilot springs

5-inch rod length designed for precise placement within the burner's flame path

this 5/8" three-way brass tee serves as a critical component for splitting or combining refrigerant lines while maintaining optimal flow characteristics and system integrity under high vibration

the RPC system often requires external sensing for optimal feedback

utilizing a high-resistance coil to precisely disconnect the start capacitor once the compressor reaches approximately 75% of its operating speed

Miscellaneous Product TS-470 Switch Els PW 17895 Spence uses a color-coding systemThe TS 470 Damper Position Switch provides open or closed position indication for compatible HVAC dampers and control assemblies. It uses an encapsulated mercury SPDT position switch mounted on a crank arm designed for a 1 2 inch horizontal damper shaft. This HVAC damper end switch changes contact state as the shaft rotates, allowing a building automation system, control panel, relay circuit, or other compatible equipment to confirm damper position.
