The position sensor includes a shift lever used to select one of five ranges P, R, N, D, and B, fixed contacts corresponding to the ranges P, R, N, D, and B, and movable contacts configured to be electrically connected to the fixed contacts. The fixed contacts include regular fixed contacts, first backup fixed contacts, and second backup fixed contacts. The first and second backup fixed contacts have their lengths in the moving direction of the movable contacts configured to be longer than the length of the regular fixed contact that corresponds to the first and second backup fixed contacts.
