ABSTRACT:
An inhibiter switch is provided with a movable body 1 rotatable in accordance with an operating position of an automatic transmission device. The movable body 1 is supported rotatably by a cover 2 and a pole base 3 having magnetic sensors 9 disposed therein. A conductive body having a terminal 7b projected into a connector section 3c at one side thereof and a body section 7a electrically connected to the magnetic sensors 9 and exposed from a bottom surface 3d, is insert molded into the pole base 3. The pole base 3 forms an offset surface 3e exposing the body section 7a as a connection location with the conductive body 7 from the bottom surface 3d. The pole base 3 has notches 3f, 3g, 3h in which the magnetic sensors 9 are disposed, and a notch 3i in which a substrate 6 is disposed. The notches 3f, 3g, 3h, 3i are formed at the periphery of the offset surface 3e. The pole base 3 also forms a guide 3j for disposing the magnetic sensors 9 within the offset surface 3e. The inhibitor switch with this construction has contact sections formed with magnetic sensors, resulting in a low manufacturing cost and a high operating precision.
