PROBLEM TO BE SOLVED: To provide a turn signal switch to definitely return the operation knob to the neutral position after it is operated. SOLUTION: The turn signal switch comprises a casing 1, an operation knob 2 capable of swaying right and left from a neutral position and being pressed down in the direction of projection from the neutral position, a restoring means (a coil spring 3 and a ball 4) for generating a restoring force to return the operation knob to the neutral position when the operation knob 2 is swayed or pressed, and an interlocking member 5 interlocking with the movement of the operation knob and forming a moving contact 6, wherein the interlocking member 5 is formed with an auxiliary means (a coil spring 7 and a ball 8) for generating a restoring force to return the operation knob 2 to the neutral position together with the restoring force by the restoring means when the operation knob 2 is swayed or pressed.
