Marketing Description - 2000: The Intermotor brand has built its reputation by engineering and distributing a full line of genuine import parts - parts that are unrivalled for quality, original look, fit, form & function, as well as coverage.. In design, we specify custom wax formulations that will expand when heated, activate a snap ac tion electrical contact and transfer the electrical signal to the fan controller. In manufacture, we custom form the wax pellets for different temperature range specifications. All units are calibrate d & tested to confirm switch actuation at their specified temperature. In production, all thermal switches are factory-calibrated to make electrical contact at the specified lower-temperature set poin t. Our switches feature a robust design with high grade materials to meet the stringent demands of today's service professional. Standard is a global manufacturer of original equipment ignition produc ts, complete quality control is maintained through the manufacturing process from componentry to finished product. The switch is designed using a formed bimetallic contact arm. The bimetal contact mov ement is achieved using the different expansion rates of two metals fused together. This is a creep action device, provides precise performance
