Abstract
A thermally responsive snap-acting switch consists of an elastic plate cantilever mounted at one end on a header, a thermally responsive element which includes a central dish-shaped portion for inducing snap action and one end of which is connected with the other end of the elastic plate in an opposed relation to the elastic plate, a support one end of which includes a portion receiving a connection between the elastic plate and the thermally responsive element so that it slides and is inclined on the receiving portion, and a projection which exerts a force on the dish-shaped portion of the thermally responsive element to calibrate the operative temperature of the thermally responsive element. The calibration is performed either by employing a screwed stud as the projection or by plastically deforming the receiving portion of the support.
