This premium thermal limit switch is a critical safety component designed for HVAC and heating systems. Acting as a high-limit control, this fan disc switch monitors internal temperatures to provide essential overheating protection. When the system reachers the critical threshold of 195°F, the bimetallic disc snaps to open the circuit, cutting power to prevent equipment damage and ensure safe operation. Ideal for residential or commercial air handlers and furnaces, this switch is a common replacement part for units experiencing frequent cycling or safety shutdowns. Its durable construction ensures a long service life and reliable temperature regulation in demanding heating applications.
