This thermal switch is designed to activate your fan relay when the fluid temperature reaches 180° F (82° C). The switch turns off when the temperature drops down to 160° F (71° C). Installs easily in any 1/8 NPT hole. 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.
