A double seesaw switch has two seesaw switches arranged side-by-side inside a case. Each of the two seesaw switches has a central terminal arranged on a bottom surface inside the case, a pair of fixed contacts separately arranged, a moving contact supported pivotably with respect to the central terminal and has a contact portion for contacting one of the fixed contacts, an operation body supported rotatably with respect to the case, and pivots the moving contact by moving on the moving contact in correspondence with a rotation movement of the operation body, and a biasing part biasing the operation body towards a neutral position. The biasing part is a leaf spring piece formed in a U shape from a portion of a ceiling surface of the case, and to press against the operation body in a power storing state of a leading end portion compressed.

A connector device is formed of a case, first and second sockets housed within the case, each having on its front surface side a recess portion into which a modular connector is inserted and having a plurality of modular terminals disposed within the recess portion and a plurality of contacts conducted to the plurality of modular terminals, respectively and resiliently protruded to different positions of a rear surface side, the first socket being rotatable within the case, and a connection member whose one surface and the other surface are respectively opposed to the rear surface sides of the first and second sockets, the connection member being disposed within the case so as to become coaxial with the first and second sockets, the connection member having on the one surface a plurality of second terminals which continuously contact with the plurality of contacts of the first socket when the first socket is rotated and having on the other surface a plurality of third terminals which are respectively conducted to the plurality of second terminals and which contact with the plurality of contacts of the second socket. Thus, the connector device becomes simple in arrangement and can be mass-produced inexpensively.

A push switch includes a sideway U-shaped spring element positioned in a recess of a holder which is precision-formed of plastic resin by molding while keeping upper and lower sections of the U-shaped spring element compressed. The lower section of the spring element being divided into an upper contact portion and a lower contact portion having a length larger than the upper contact portion. The contact spring element is then housed in a casing provided with fixed contacts. The contact spring element being pivotally supported though a support shaft in the casing while contacting the lower contact portion with a first fixed contact and striking an upper plate of the holder against a stopper to stop upward pivotal movement of the holder due to the restoring force of the spring element.
