ンスイツチ。 In a pushbutton switch in which two circuits of contacts are arranged corresponding to one pushbutton, four pairs of contacts are formed by placing copper foil patterns close to each other on a printed circuit board and are arranged at equal intervals on the circumference. a fixed contact, four conductive movable contacts arranged opposite to these four pairs of fixed contacts with a slight spacing therebetween, and these movable contacts exert an elastic restoring force in the direction in which the push button is pressed. A push button switch comprising a rubber sheet attached so as to have a contact point of two circuits by connecting diagonally located fixed contacts of the four pairs of fixed contacts in parallel to each other.
