    • PROBLEM TO BE SOLVED: To provide a switch capable of elongating a life and improving shock resistance by suppressing a load to a movable electrode while meeting a request for miniaturization.SOLUTION: A case 2 mounted on a circuit substrate includes a recess 2a. A plurality of fixed electrodes 3a, 3b and a movable electrode 5 are disposed in the recess 2a. The movable electrode 5 can be displaced between a first position allowing the plurality of fixed electrodes 3a, 3b to be mutually in conduction states and a second position allowing them to be in non-conduction states. A pressing member 6 is disposed to cover the recess 2a, and displaces the movable electrode 5 from the second position to the first position by external pressing force. By the elastic deformation of the pressing member 6 by the pressing force, a contact area between with the movable electrode 5 increases.
    • 要解决的问题:提供一种能够延长寿命并且通过在满足小型化的要求的同时抑制对可动电极的负荷来提高抗冲击性的开关。 安装在电路基板上的壳体2包括凹部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可以在允许多个固定电极3a,3b相互导通状态的第一位置和允许它们处于非导通状态的第二位置之间移位。 按压构件6设置成覆盖凹部2a,并且通过外部按压力将可动电极5从第二位置移动到第一位置。 通过按压力的按压构件6的弹性变形,可动电极5之间的接触面积增大。 版权所有(C)2013,JPO&INPIT
