ABSTRACT:
A pressure switch comprising a housing, a first contact mounted in the housing and a support mounted in the housing in spaced relationship to the first contact. A pressure responsive member is mounted in the housing for moving a second contact into and out of engagement with the first contact and with the support. A first spring urges the pressure responsive member in opposition to the fluid pressure acting on the pressure responsive member. The pressure responsive member includes a bistable spring which carries the second contact. The bistable spring augments the first spring as the pressure responsive member moves from a low pressure position toward a high pressure position and opposes the first spring as the pressure responsive member moves from the high pressure position toward the low pressure position.
