Carrier HH18HC350 Rollout Switch SPDT 350°F

The Carrier HH18HC350 Rollout Switch is a crucial safety component designed specifically for Carrier furnaces. This tiny switch, measuring only 2" long, 1.4" wide, and 1.2" high, packs a powerful punch in protecting your furnace from overheating. Inside the switch is a spring-loaded mechanism and a temperature-sensitive coil. When the furnace temperature exceeds a designated safety limit (typically 350°F in this case), the coil expands, tripping the switch. This interrupts power to the burner, shutting down the furnace and preventing potential damage from overheating. By automatically stopping the burner in high-temperature situations, the Carrier HH18HC350 Rollout Switch plays a vital role in protecting your Carrier furnace and your home from safety hazards.
