要約
(EN)
A switching device which can be small-sized by improving a shielding performance and can improve the reliability of switching characteristics. A permanent magnet 77 disposed near stationary contacts 78a and 78b is arranged in its pole-face 77a perpendicularly of the axis of a moving contact member.

(ZH)

本发明提供一种在提高切断性能并使装置小型化的同时,提高开闭特性可靠性的开关装置。其中,使在固定接点(78a、78b)的附近设置的永久磁铁(77)的磁极面(77a)和可动接触片的轴心垂直相交地配置。
