Abstract
The problem of providing plurality of different models of pressure switches to suit the requirements of a plurality of differing manufacturers may be minimized or eliminated in a pressure switch, including a frame (20), a diaphragm (50) secured to the frame (20) and adapted to be exposed to a mechanical source of fluid under pressure, such as a compressor, and electrical contacts (64), (66), (70) mounted on the frame (20) for relative movement toward and away from each other between open and closed positions. A lever system (72), (80) is mechanically interposed between the diaphragm (50) and the contacts (64), (66), (70) for effecting the previously mentioned relative movement and an unloader valve (110) is mounted on the frame (20) and adapted to be connected to the source of pressure fluid and operable when the contacts (64), (66), (70) are in an open position to vent fluid under pressure from the source. The system includes a bell crank (118) responsive to the lever system (72), (80) for operating the unloader valve (110) and the frame (20) is provided with at least two spaced mounting elements (116), (164), (166), (168) for mounting the unloader valve (110) with the bell crank (118) being selectively mountable at points (126), (127) adjacent either of the mounting elements (116), (164), (166) and (168).
