ABSTRACT:
In a position detecting switch, a first movable contact is disposed in a first receptacle formed in a sliding body and is urged toward a casing member by a first spring so as to engage first and second stationary contacts mounted in the casing member when the sliding body is in a selected position. In order to prevent non-contact due to rotating moment of the first movable contact relative to the stationary contacts one or more features for inhibiting or reducing the relative moment are provided such as: (1) The first and second stationary contacts can be urged toward the first movable contact by fourth and fifth springs. (2) An elastic member or members can be disposed in a clearance between end walls of the sliding body and walls of the first receptacle. (3) The first spring can be restrained to apply its load to a substantially middle portion of the movable contact. (4) A plurality of the first springs can be provided to apply load the movable contact at a plurality of locations in a lengthwise direction. (5) An interval between the first and second stationary contacts can be increased. (6) An auxiliary receptacle member can be provided in the contact receptacle in the sliding body. (7) A lid can be disposed in the opening of the contact receptacle and have an opening larger than the movable contact but smaller than the contact receptacle.
