Claims

[Claims for Utility Model Registration] (1) A pressure switch comprising a pressure chamber partitioned by a diaphragm in a switch body and a ventilation section that forms a switch chamber and is connected to the switch chamber, wherein the switch chamber comprises: A contact holder that responds to the displacement of the diaphragm, a movable contact piece having an annular contact portion that responds to the displacement of the contact holder, a coil spring that presses the movable contact piece against the contact holder, and a coil spring that presses the movable contact piece against the contact holder. A connection terminal connected to the movable contact piece, and at least two contacts that come into contact when the movable contact piece provided on the outer periphery of the annular contact portion of the movable contact piece are in ON operation and separate when they are in OFF operation. A pressure switch characterized in that it has a fixed connection terminal, and a pressure switch. (2) The fixed connection terminal having the at least two or more contacts is rectangular, one of which is continuous on the inner periphery of the annular disk, and the other is extended in a direction substantially perpendicular to the plane of the annular disk, and the fixed connection terminal is further formed of the rectangular shape. The tip extends in a direction substantially parallel to the plane of the annular disk, and is turned on so as to face the annular contact portion of the movable contact piece. 2. The pressure switch according to claim 1, which is a connection terminal having at least three fixed contact portions that are turned off.
