Application
This limit switch is designed to protect HVAC heating systems from overheating conditions. When the sensed temperature reaches the 160°F open threshold, the switch opens to interrupt the control circuit and shut down the heating source. Once temperatures drop back to 140°F, the switch automatically closes and restores normal operation — providing continuous, hands-free thermal protection.
