Fan Thermostat Temperature Switch, Keenso 185 to 175 Degree Gold Electric Engine Cooling Fan Thermostat Temperature Sensor Switch with 3/8" Pipe Thread for 10" 12" 14" 16" Fan

I'm delighted to be of assistance. Our fan thermostat temperature swith is universal fit and does not require a specific thread pitch.

I'm delighted to be of assistance. This fan thermostat switch will not function as a coolant temperature sensor, sorry.

You use it to turn on the relay's ground wire. When the coolant temperature reaches 185 degrees Fahrenheit, the thermostat grounds the wire that is connected to it. I realized as I was writing this that you were probably asking if you could use this as a fan ground switch. I wouldn't do it. Maybe a couple of times it will work. However, I seriously doubt that it is designed to handle real current.

On the market, there are basically two types of sensor/sender probes, plus a third, less commonly used sender that combines both properties of what I call a thermal switch (such as to fire an indicator light in the instrument panel) and can be used to simply turn on/off a radiator fan or trigger an instrument panel warning light; and the other, which was designed for use in analog applications with variable resistance and current. a meter or a temperature gauge While both will behave as if they are analog when tested, only this type of switch (on or off) has the triggering on/off property. There is a hysteresis that causes the fan to turn on at a specific temperature. However, it turns off when the temperature falls below the threshold at which it was turned on. Otherwise, at the threshold temperature, it would become jittery and appear unstable. Thx
