ABSTRACT:
A press-button switching device includes a housing, stationary and movable contacts mounted in the housing, an actuating member constructed as a press-button which is guided during its switching movement in the interior of the housing and which moves the movable contacts into the respective switching positions thereof. A compression spring is arranged between the actuating member and the housing, wherein the actuating member is movable into the housing against the force of the spring. The movable contacts are each constructed as a bridge-forming contact which bridges two strip conductors in the switched-on position. During the inwardly and outwardly directed movements of the actuating member, the bridge-forming contact is moved along the strip conductors. At its end contacting the actuating member, the compression spring continues as a spring arm whose free end resiliently presses the bridge contact against the strip conductors.
