Product Details

Description

This high-performance high limit control switch is an essential safety component for residential and commercial heating systems. Designed as a normally closed (NC) thermal safeguard, it monitors internal air temperatures to prevent overheating in furnaces and air handling units. If the temperature reaches its designated threshold, the switch automatically breaks the electrical circuit to protect the equipment from damage and ensure safe operation. Once the system cools down, the auto-reset feature restores the connection without the need for manual intervention. This durable SPST (Single Pole Single Throw) sensor is ideal for maintaining the reliability and longevity of HVAC equipment, providing peace of mind through precise thermal regulation.
