<p>A holder incorporated in and fixed to cylindrical lever body rotatably supports a rotating knob, and the rotating knob supports a pressing knob so as to be able to reciprocate in the axial direction. Any of these cylindrical lever body, the rotating knob and the pressing knob has a non-circular outline along an orthogonal plane which is orthogonal to the axial direction. The rotating knob is arranged in the vicinity of the distal end of the cylindrical lever body, and the rotating knob opposes a main surface of a circuit board mounted on the holder. The main surface of the circuit board includes a push switch having a contact pattern which can be connected to and disconnected from a slider attached to the rotating knob, and a driven part thrust by a drive rod of the pressing knob during a pressing operation.</p> |
