Abstract

　操作ロッドが破損した場合や、操作部が破損したり脱落した場合であっても確実に開閉器を開状態にして安全性の向上を図ることができる安全スイッチ、安全リミットスイッチ、セレクタスイッチ、押ボタンスイッチなどのスイッチ装置を提供する。 　開閉器３９の可動接点３９ａがコイルバネ５０によって固定接点３９ｂに対して開離方向に付勢されている。そして、アクチュエータ３の操作部５への進入に伴う駆動カム１５の回転により、連結部２２がコイルバネ５０の付勢力に抗しつつガイド溝１５ｄに沿って移動することにより操作ロッド２１が移動して開閉器３９を閉状態に切り換える。したがって、コイルバネ５０により操作ロッド２１が下方に付勢されて可動接点３９ａが固定接点３９ｂに対して開離方向に付勢されるため、操作ロッド２１が破損した場合や、操作部が破損したり脱落した場合であっても開閉器３９を確実に開状態とすることができ、安全性の向上を図ることができる。
