ABSTRACT:
An adjustable pressure responsive switch assembly includes a unitary slide cam and button with projections extending outwardly from the slide cam. The support bracket mounted on the pressure switch includes an elongated slot having an enlarged opening at one end. The slide cam projections are adapted to be inserted in the enlarged opening and then be slidingly received in the elongated slot. The slide cam cannot be removed from the bracket unless it is moved all the way to one extreme so that the projections can be removed from the enlarged opening. This movement is prevented by stops formed as part of the cam.
