A movable contact 4 is fabricated of a spring wire, the halfway portion of which is wound around a pin 5. One lengthwise end of the wire rests on a casing and the other lengthwise end is rested at the halfway portion of an L-shaped lever 6 received by the pin 5, the pin being coaxial with the movable contact 4. A fixed contact 7 is disposed at a position where it can engage the movable contact 4 at its portion halfway between the point rested on the lever 6 and the portion being wound around the pin. A portion or arm of the lever 6 can extend toward and contact a pickup 3 returned to the starting point of sound reproduction. That portion of the lever 6 is spaced from the pin 5 a distance longer than the part or arm of the lever 6 associated with the movable contact 4. By virtue of this construction, the device is able to perform exact switching action without requiring any particular delicate adjustment in connection with the resilient force of each return or coil spring 1.
