Claims

[Scope of Claim for Utility Model Registration] ■ A diaphragm is airtightly fixed between an upper body and a lower body having a pressure introduction port to form a pressure receiving chamber in the upper body, and a diaphragm is attached to the ash pressure receiving chamber side of the diaphragm. In a switch that has a piston that moves up and down due to the pressure applied to the switch, and a holder that engages with the piston and is biased by a spring from below, the switch has an integral fixed terminal whose lower end protrudes outside the lower body, and an inverted terminal. A two-action pressure switch characterized in that an electric opening/closing section is constituted by a leaf spring to which return and reversal motion of a disk is transmitted via a rod. (2) The switch is composed of contacts attached to both ends of linearly connected leaf springs at different heights, and fixed contacts attached at different heights to the upper ends of fixed terminals. Actuated pressure switch. ■ The switch consists of contacts in which the tips of a pair of leaf springs, each with its rear end attached to the top of a pair of fixed ends at different heights, move toward and away from each other.The upper contact is actuated by a piston, and the lower contact 2. The two-action pressure switch according to item 1, wherein the switch is actuated by reversing the reversing disk via the rod.
