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