Abstract
A pressure responsive assembly including an actuator rod coupled to a pressure source through a rolling type diaphagm. The other end of the actuator rod is connected to a wiper assembly. A first part of the wiper assembly contacts a coil of resistance wire to provide a first signal indicative of the pressure. A second part of a wiper assembly moves into and out of contact with a switch contact pad as the sensed pressure crosses a predetermined threshold value.
