ABSTRACT:
This pressure sensitive switch includes a bellows made of corrosion resistant material and with a hollow cylindrical body, which defines a pressure receiving surface on the outer surface of its one closed end portion, and with an open end which is fixedly secured to a fixed member in such a manner that the bellows may expand and contract in its longitudinal direction in response to small changes in the pressure difference between its interior space and the space outside it; a plunger mounted so as to reciprocate in response to the expansion and contraction of the bellows by being acted upon by the inner surface of the bottom portion of the bellows; and a switch assembly which is switched to and fro in response to the reciprocating motion of the plunger. This construction is compact and efficiently functional.
