Abstract

　操作ロッドが破損したり、操作部が破損した場合に開閉器を開状態にすることで安全性の向上を図るとともに、簡易な構成で小型化を図ることができるスイッチ装置を提供する。 　操作ロッド５の第２の位置を越える上方への過剰移動に連動して開離部材６０が固定接点３９ｂと可動接点３９ａとを開離するため、開閉器３９は確実に開状態に維持される。したがって、何らかの異常が発生して駆動カム１５による操作ロッド２１のスイッチ部７の方向への押し込みが解除されても、開離部材６０が開閉器３９を開状態とするため安全性の向上を図ることができる。また、操作ロッド２１の第２の位置を越える操作部５の方向への過剰移動を検出するために開閉器を別途設けたりしなくともよいため、簡易な構成で安全スイッチの小型化を図ることができる。
