Abstract
An inhibitor switch comprises a movable board (1) having a movable arm (1b) carrying a permanent magnet (4) and being rotatable in accordance with a selected position of an automatic transmission, a magnetic sensor (9) detecting magnetic lines of force of the permanent magnet (4), a base board (3) having the magnetic sensor (9) mounted thereon and having the movable board (1) rotatably supported thereon, and a lid (2) having the movable board (1) rotatably supported thereon. The permanent magnet (4) is urged by a spring (13) toward the magnetic sensor (9). The movable board (1) includes a hollow shaft (1a) and the movable arm (1b) which are in one piece construction. The movable arm (1b) has the permanent magnet (4) and projections (1f, 1g) and a blind hole (1j). The projections are provided on one surface of the movable arm facing the base board (3) in pressure contact with the base board (3). The blind hole (1j) is formed in the other surface of the movable arm (1b) facing the lid (2) and receives a pressure-contact (14) inserted together with the spring (13) therein. As a result, an inhibitor switch is provided that has magnetic sensors and is inexpensive and highly reliable.
