Claims

[Scope of utility model registration request]

a common terminal; first and second fixed contacts branched into two from the common terminal and integrally provided; and first and second fixed contacts arranged correspondingly to the first and second fixed contacts to perform a switching operation. A second movable contact/return spring and first and second switch terminals electrically connected to the first and second movable contacts/return springs are assembled into a switch housing, and the switch housing The paired push switch has first and second pushbuttons that operate the first and second movable contacts and return springs by an external force, which are slidably penetrated through the pushbutton switch, and the pushbutton switch is connected to the common terminal. The first and second fixed contacts are formed by bending each end of each of the two branches from the common terminal into a Y-shape.
The movable contacts and return springs each include first and second torsion springs, and one end of the first and second torsion springs is pushed into the recess of the first and second fixed contacts having the Y-shape. The first and second torsion springs are respectively formed as first and second movable contacts, and the other ends of the first and second torsion springs are respectively formed as the first and second switch terminals. A pair of pushbutton switches, characterized in that the pushbutton operators are provided at positions for operating the first and second movable contacts, respectively.
