The present invention provides, in a preferred embodiment, a thermostatic switch having a bimetal blade connected, at one end, to a terminal arm by means of a fastener. In accordance with the present invention, a weld electrically connects the one end of the blade to the terminal arm. The weld is located so that the fastener is located between the weld and a central, flexing portion of the bimetal blade. As a result of the placement of the weld and the fastener, weakening of the central flexing portion of the blade does not occur as is the case of a prior art connection in which the blade is welded to terminal arm.
