  • Low cost fluid pressure responsive electric switch having increased longevity
    Patent number: 6091034
    Abstract: A fluid pressure responsive electrical switch (10) is shown having a generally flat base (12) formed with an annular recess (12e) which receives therein the distal free end of a cup-shaped resilient membrane (16) captured by the distal free end of a tubular sidewall (14a) of housing (14). Membrane (16) defines a dampener chamber (16d) having a constricting orifice (12f) to a fluid pressure receiving portion (12d) of the switch. The top wall (16a) of the membrane is adapted to transfer fluid pressure to a snap-acting disc (18) which, when actuated by a selected high pressure build-up within the dampener chamber, will in turn engage the bight (22f) of movable contact arm (22c) and move the movable contact arm to separate movable contact (26) from stationary contact (24) mounted within a switch chamber (14d) of housing (14).
