ABSTRACT:
A normally open pressure responsive electrical switch is shown having upper and lower body members with a combination terminal and disc seat member sandwiched therebetween. An electrically conductive snap acting disc is disposed on the disc seat and is adapted to snap through a centrally disposed aperture in the terminal into electrical engagement with an electrical contact disposed on a terminal mounted in the lower body member. The upper body member has a bore extending therethrough and slidably mounts a pressure converter adapted to convert pressure from a pressure source to a force and apply the force to the disc. A flexible membrane is disposed over the bore with an O-ring received on an O-ring seat adjacent the bore in the upper body member. A wall extending around the seal seat is deformed to capture the O-ring at its seat.
