Claims (3)

  1. 내장스위치를 조작하는 조작플런저와 회전축에 감합된 캠을 접접시키고, 회전축의 회동으로 캠을 개재하여 조작플런저를 상하동시키고, 내장스위치를 절환하는 동시에 회전축을 동작위치와 복귀 위치와의 두 위치에서 유지하도록 한 리미트 스위치에 있어서 상기 회전축과 캠과의 사이에 소정각도 상대회전이 자유로운 유극을 형성한 것을 특징으로하는 리미트 스위치.
  2. 제1항에 있어서, 상기캠의 조작 플런저와 접접면 중 동작한도위치에 조작 플런저의 두부가 감합되는 흠부를 형성한 것을 특징으로 하는 리미트 스위치.
  3. 제1항에 있어서, 상기 회전축을 어느 한쪽방향으로 부세력을 부세하는 가동 플런저와 상기회동축의 사이에 강구를 개재시킨 것을 특징으로 하는 리미트 스위치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
