Abstract
A temperature switch assembly which includes a bimetal element inserted into a holder body and secured in place by a mating shell is presented. The holder body is constructed so that it may be screwed into existing bore holes of the vessel or engine. The bimetal element is formed with tangs on its base so that expansion and contraction effects due to temperature changes are compensated thus ensuring calibration of temperature switch over prolonged usage. The mating shell includes a switch contact. When the bimetal element reaches a predetermined temperature, the bimetal element makes contact with the switch contact and completes the circuit. The circuit is connected to a warning device which is actuated when the circuit is completed.
