BWD is an aftermarket leader, providing a premium line of engine management products. We are constantly evolving to give BWD customers the competitive edge they need to compete in today’s ever-changing marketplace.
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 manufacture, 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
Our switches feature a robust design with high grade materials to meet the stringent demands of today's service professional
