(2) a diaphragm that is displaced by the pressure of a fluid; a switching means that is turned on and off by movement in the same direction as the displacement of the diaphragm; and a switching means that is biased toward the diaphragm from the switching means side, and a switch drive mechanism that operates in response to the displacement of the fluid and operates the switching means multiple times while the diaphragm is displaced in one direction, wherein the diaphragm is not displaced by the pressure of the fluid. 1. A pressure switch comprising a biasing means for biasing the diaphragm in the same direction as the direction in which the fluid pressure is applied, in order to sometimes regulate the rest position of the switch drive mechanism.
