Description:
TEMP SENDER/SW
Every coolant fan switch in our offering is a direct-fit replacement, manufactured to the exact resistance and temperature ratings as the OE, to ensure switching at the correct temperature to keep cooling systems functioning properly.. This switch is engineered to carry a high electric current in order to send the message to increase or decrease airflow for temperature control to prevent engine shutdown due to overheating.. Our switches are made using only the most durable materials, such as metal housings and high temperature wire covers to ensure that you receive a longer lasting part.. Robust design and high grade materials meet the stringent demands of today's service professional. In design, we specify custom wax formulations that will expand when heated, activate a snap action electrical contact and transfer the electrical signal to the fan controller. In manufacturing, we custom form the wax pellets for different temperature range specifications. All units are calibrated & tested to confirm switch actuation at their specified temperature. The 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 performance. In production, all thermal switches are factory-calibrated to make electrical contact at the specified lower-temperature set point.
