How Limit Switches Work
A limit switch monitors the temperature within the heat exchanger or supply air plenum. If temperatures rise above the safe operating threshold — in this case, 190°F — the switch opens to cut power to the burner or heating element, preventing overheating, heat exchanger damage, or fire hazard. Once temperatures fall back to the reset point (160°F), the switch closes and normal operation resumes.
Application
- Sterling HVAC forced-air furnaces and unit heaters
- High-limit overheat protection in residential and commercial heating systems
- OEM replacement in equipment requiring a 190°F open / 30°F differential limit switch
