Product Features:Custom wax formulations that will expand when heated, activate a snap action electrical contact and transfer the electrical signal to the fan controllerThe switch is designed using a formed bimetallic contact arm. The bimetal contact movement is achieved using the different expansion rates of two metals fused together. This is a creep action device, provides precise performanceIn production, all thermal switches are factory-calibrated to make electrical contact at the specified lower-temperature set pointRobust design and high grade materials meet the stringent demands of today's service professional
