The concave streak portion, in which the welding inclination surfaceis formed, is provided on the side wall; the projecting portion, which is fitted into the concave streak portionwhen the substrateand the lid bodyoverlap to form the switch case, is provided on the lid body; when the substrateand the lid bodyare overlapped, the switch caseis sealed by contacting the seal ringwith the flange portionand the welding shoulder portioninterferes with the welding inclination surface; the substrateand the lid bodyare jointed by melting the interference portion by high-frequency welding; the release region K, which keep the communicating state of the inside of the switch casewith the outside is designed by notching the projecting portionfrom the root thereof.

Switch

A neutral start switch has a base on which stationary contacts are arranged and a rotor on which movable contacts capable of contacting the stationary contacts are disposed. The stationary contacts include reverse lamp contacts connected to a reverse lamp lighting circuit, position stationary contacts connected to a position signal circuit provided in an electronic control device, and starter stationary contacts connected to a starter motor driving circuit. The contacts are arranged so that contact portions of the movable contacts that contact the reverse lamp stationary contacts are different from contact portions of the movable contacts that contact the other stationary contacts, thereby preventing carbonized powder produced by spark at the time of the closure and opening of the reverse lamp contacts from causing a contact failure of another contact.

Neutral start switch

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.
