Product Details

Description

This 3-inch high limit control switch is a critical safety component designed for HVAC systems and residential heating appliances. Functioning as a thermal cut-off, it monitors internal temperatures to prevent overheating and potential equipment damage. When the system reaches a specific temperature threshold, the switch automatically interrupts the electrical circuit to shut down the heat source. Once the appliance cools down by a set differential, the switch resets to allow for normal operation. This reliable thermal safety limit ensures your furnace or heating unit operates within safe parameters, providing essential protection for your home’s climate control system.
