• As a global manufacturer of original equipment ignition products, we maintain complete quality control throughout the manufacturing process from componentry to finished product
• 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.
• 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 and 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 point
• 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
• 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
• 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.
