    • PROBLEM TO BE SOLVED: To provide a switch which inhibits a load to a movable electrode, achieves the long life, and improves the impact resistance while meeting a demand for the downsizing.SOLUTION: A case 2 mounted on a circuit board has a recessed part 2a. Multiple fixed electrodes 3a, 3b and a movable electrode 5 are disposed in the recessed part 2a. The movable electrode 5 displaces between a first position where electric continuity is established between the multiple fixed electrodes 3a, 3b and a second position where the electric continuity is not established. A pressing member 6 is disposed covering at least a part of the recessed part 2a and displaces the movable electrode 5 from the second position to the first position with a pressing force from the exterior. A buffer member 7 is disposed between the movable electrode 5 and the pressing member 6 and is elastically deformed by the pressing force.
    • 要解决的问题:为了提供抑制对可动电极的负载的开关,可以实现长寿命,并且在满足小型化的要求的同时提高耐冲击性。

      解决方案:安装在电路板上的壳体2具有凹部2a。 多个固定电极3a,3b和可动电极5设置在凹部2a中。 可动电极5在多个固定电极3a,3b之间建立了电连续性的第一位置与电连续性不成立的第二位置之间移位。 设置有压紧构件6,其覆盖凹部2a的至少一部分,并且利用来自外部的按压力将可动电极5从第二位置移位到第一位置。 缓冲构件7设置在可动电极5和按压构件6之间,并且通过按压力弹性变形。 版权所有(C)2013,JPO&INPIT
