A diaphragm is airtightly fixed between a pressure introduction body and an assembly switch body to form a pressure receiving chamber, and an electric switch is provided in the assembly switch body, wherein the assembly switch A double piston is provided in the main body which is pressed against the diaphragm by spring force, the outer piston faces a low pressure leaf spring through a low pressure rod, and the inner piston faces a high pressure rod for a high pressure leaf spring through a reversing plate. Two-action pressure switch with opposing sides. 2. The assembly switch main body is formed in a cylindrical shape with a central partition wall, and a double piston consisting of an external piston 3 and an internal piston 4 is pressed into the upper compartment by a spring 8 via a holder 5.
Further, a reversing plate 11 is provided so as to be able to come into contact with the internal piston 4, and a low-pressure leaf spring 12 and a high-pressure leaf spring 13 are provided in the lower compartment with their contact points facing each other, one end of which is connected to the external piston 3. A low-pressure rod 9 to which is fixed passes through the internal piston 4, the holder 5 and the central partition wall, and the other end touches the low-pressure leaf spring 12,
The high-pressure rod 10 whose end touches the high-pressure leaf spring 13 passes through the low-pressure leaf spring 12 and the central partition wall, and the other end faces the reversing plate 11 so as to be able to come into contact therewith. Two-action pressure switch as described.
