Claims

[Claims for Utility Model Registration] 1. A switch body, a flexible diaphragm disposed in the switch body that is displaced in response to fluid pressure, and the diaphragm is biased in a direction opposed to the direction in which the fluid pressure acts. a movable contact member made of an elastic material that deforms in accordance with the displacement of the diaphragm; a first fixed contact that is spaced apart from the movable contact member; and a first fixed contact that is provided on the switch body and contacts the movable contact member in a steady state, and when the movable contact member is deformed by a larger amount than the predetermined amount of deformation. a second fixed contact spaced apart from the pressure switch. 2. A switch body, a flexible diaphragm disposed on the switch body that is displaced in response to fluid pressure, and a diaphragm disposed so as to bias the diaphragm in a direction opposed to the direction in which the fluid pressure acts. a movable contact member made of an elastic material that deforms in response to a second fixed contact, which is provided on the switch body and is separated from the movable contact member in a steady state and comes into contact with the movable contact member when the movable contact member is deformed by a larger amount than the predetermined amount of deformation; A pressure switch equipped with.
