SWITCHING ARRANGEMENT

PROBLEM TO BE SOLVED: To provide a switching arrangement capable of preventing generation of noises due to an external force such as vibrations.SOLUTION: The switching arrangement includes: a support body 12 which is mounted with an operation member 13 vertically movable on the upper face thereof; a switch contact 14 that makes an electrical connection/disconnection according to a vertical movement of the operation member 13; a wiring board 15 mounted with the switch contact 14; and a lower case 10B disposed below the wiring board 15. The wiring board 15 is held between the support body 12 and the lower case 10B. The lower face of the support body 12 is abutted on the upper face of the wiring board 15 plural lower projections 17 are formed on the upper face of the lower case 10B for pressing the lower face of the wiring board 15. 【課題】振動などの外力に伴ってスイッチ装置が発する雑音を抑制することを目的とするもの。【解決手段】操作体１３が上面に上下動可能に装着された保持体１２と、操作体１３の上下動に応じて電気的接離を行うスイッチ接点１４と、スイッチ接点１４を実装した配線基板１５と、配線基板１５の下方に配置された下側ケース１０Ｂとを備え、配線基板１５は保持体１２と下側ケース１０Ｂとの間に保持され、保持体１２の下面が配線基板１５の上面に当接すると共に、下側ケース１０Ｂの上面に配線基板１５の下面を押圧する複数の下側突起部１７を設けた。【選択図】図１
