Product Description

This OEM approved replacement part is compatible with various models of Sunheat appliances. For full compatibility, please see the "Model Cross Reference List" below. The purpose of the switch is to turn the device on/off, as well as playing a role in electric breaking by momentarily reversing electrical polarity. Due to the mechanical internals of switches, they tend to degrade and wear out over time, making them a commonly replaced part. Common symptoms of a broken switch include: the device has completely stopped functioning, it will not turn on, and turning off intermittently during use. This switch has 3 prongs coming out of the back and can be removed by squeezing the two tabs on the side of the Switch. Switches are sold individually.

Hi Bill, thank you for reaching out. The positive terminal is connected to the fuse block and the other to the battery depending upon the appliance, the second accessory terminal is connected to the LED or light bulb, and the third terminal is connected to the ground or negative. We hope this information is useful!

Heater switch.
Looked and performed as the original switch. As it was a bit larger than the original, it did require grinding a bit off the heater housing to make fit.
