This compact contoller switch assembly mounts in any 12AN hose to turn your electric fan on and off automatically.
The black anodized adapter fitting has a 12AN male fitting on one end and a 12AN female swivel on the other. Simply disconnect your existing hose from a fitting (for example, where the hose attaches to the cooler) and install this fitting between the two. The included thermal switch activates your fan relay when the fluid temperature reaches 190° F (88° C). The switch turns off when the temperature drops down to 170° F (77° C). Two 1/4" spade terminals make electrical hook up easy.
Note: This switch is not rated for the current draw of the fan. It must be used to control a fan relay.
Fan and relay are not included.
