Switch device

Abstract

Abstract PURPOSE:To make it possible to perform a two-phase operation in which after one side switch element is turned on, the other side switch element is turned on, by setting the springing forces of the first and the second restoration spring members almost equal, and setting the operation point to which an external operation force is applied at the position slipped a little from the center position of movable contact holders. CONSTITUTION:An operation member 27 to deliver an external operation force to movable contact holders 16a to 16d of the first and the second switch elements 21 and 22 which are arranged in parallel each other is provided on condition loading between the movable contact holders. After that, the first and the second restoration spring members 17a to 17d to give restoration springing forces to the movable contact holders 16a to 16d are set to have almost equal springing forces. And the operation point where an external operation force is applied at the operation member 27 is set slipped from the center position between the movable contact holders 16a to 16d. As a result, a two-phase operation in which after the first switch element 21 is turned on, the second switch element 22 is turned on, can be obtained, and a phase feeling can be generated when each switch element is turned on.
