<p>Provided is a stalk switch device which does not cause a contact failure of a switching device of an operating ring upon rotating and is suitable for a long life-span. The stalk switch device is configured such that a permanent magnet (9) is fixed to a driven member which is driven by rotation of an operating ring (7), and a change in magnetic field caused by the movement of the permanent magnet (9) is detected by a giant magnetoresistance (GMR) sensor (12) mounted on a circuit board (3) in a housing (1) The operating ring (7), the driven member, and the circuit board (3) are retained by a holder (2), and the holder (2) is fixed to the housing (1). As the driven member, for example, a cylindrical rotating member (8) formed integrally with the operating ring (7), a rotation shaft member (23) rotated by a driving gear (22) which is rotated along with the operating ring (7), or a slider (21) which is driven by a rotating driving member (20) which is rotated along with the operating ring (7) to move linearly, is used.</p> |
