This premium 3/4-inch disc limit switch is a vital safety component designed for HVAC systems and heating appliances. Functioning as a high-limit control, it monitors internal air temperatures to protect your equipment from overheating. The switch features an automatic reset mechanism that interrupts the electrical circuit when the temperature reaches its 200°F limit and restores operation once the temperature cools by 40°F. Ideal for maintaining the safety and efficiency of furnaces, unit heaters, and air handlers, this bimetal disc switch provides reliable thermal protection and prevents potential damage caused by excessive heat build-up. Replacing a faulty limit switch can resolve issues with short-cycling or safety shut-offs in residential and commercial heating units.
