Abstract:
A rotating electrical component, comprising:a support member having a flange, said flange of said support member having a support member flange surface,an operating shaft rotatably and axially movably mounted on said support member and having a flange, said flange of said operating shaft having a operating shaft flange surface, said operating shaft flange surface being adjacent to said support member flange surface, anda spring member for pressing said operating shaft in a direction so as to bring said support member flange surface into contact with said operating shaft flange surface;wherein at least two projections are formed on either said support member flange surface or said operating shaft flange surface, said projections being located on different sides of an axis of rotation of said operating shaft, said projections each having a different radius from said axis of said operating shaft so that said projections will not overlap each other in a circumferential direction around said axis of said operating shaft, and further wherein at least two recesses are formed on either said support member flange surface or said operating shaft flange surface, said recesses each having a different radius from said axis of said operating shaft so that said recesses do not overlap each other in the circumferential direction around said axis of said operating shaft, said recesses being located so as to be engageable by said projections to prevent rotation of said operating shaft, and said projections are disengageable from said recesses when said operating shaft is moved axially against the force of said spring member to enabling rotation of said operating shaft.
