A pressure switch is shown as having two terminals extending externally of a switch housing within which are two stationary adjustably prepositioned fixed contacts respectively electrically connected to the two terminals; two movable contacts are also situated within the housing and, in response to sensed pressure, move toward (or away from) the fixed contacts in a manner causing sequential closing of electrical circuit portions as between respective movable contacts and fixed contacts; related electrical circuit means electrically connected to such contacts serves to energize and/or de-energize related output means as, for example, electrically operated clutch means.
