摘要： A new Automatic Thermal Shut-Off Switch for preventing heat damage to a high pressure low volume water pump. The inventive device includes a T-shaped housing having a longitudinal cavity, a bimetallic compression spring within the cavity, a disc within cavity on top of the spring, a pin orthogonally secured to the disc, a first contact, and a second contact electrically in contact. The housing is positioned within an unused port within a pump housing and conducts the heat produced by the pump. The conducted heat expands the spring thereby forcing the pin upwardly to separate the first contact from electrically contact with the second contact.
