ABSTRACT:
A hermetically sealed, creep acting pressure switch has a sensor assembly comprising a bulged metallic membrane welded between a port fitting and a support. A switch assembly, attached to the sensor assembly, includes a housing which has a switch chamber in which, in one embodiment, a pair of stationary contacts are mounted. A piston having a force receiving surface at one end is biased into engagement with the membrane with an adjustable calibrated force. An electrically conductive contact bridge is mounted on and is movable with the piston. The switch can be normally open or normally closed depending on which side of the contact bridge the stationary contacts are mounted. In an alternate embodiment a miniature switch is mounted in the switch chamber and is adapted to be actuated by the piston.
