A turn signal switch includes a housing having a cam portion; a control lever turnably supported in the housing; a driving element for holding the control lever at three positions, first and second operating positions and a neutral position, in cooperation with the cam portion; a lever member turnably supported in the housing so as to return the control lever from the first and second operating positions to the neutral position; and a spring member for elastically urging the lever member toward a canceling projection that turns together with the steering wheel. The lever member is retracted outside the locus of turning of the canceling projection by the control lever when the control lever is in the neutral position, and is advanced inside the locus of turning of the canceling projection by the urging force of the spring member so that the spring member is in elastic contact with the lever member at one point when the control lever is in the first or second operating position. |
