Field of the Invention The present invention relates to a semi-automatic limit switch installed in a production facility or construction and industrial machinery field and used to temporarily or emergency stop the operation of a mechanical device or the like by an artificial method (manual).

이를 좀 더 상세히 설명하면, 덮개가 덮어지는 스위치본체의 내부에는 신호(전원)선이 접속되는 한 쌍의 고정단자를 이격시켜 고정 설치하고, 고정단자의 사이에는 작동단자판이 구비된 작동지지관을 설치하되 작동지지관의 내부 수직 선상에는 유통공을 뚫어 작동봉을 삽입시켜서 된 것으로, 고정단자에 신호(전원)가 입력되면 작동봉이 삽입된 작동지지관과 함께 작동단자판이 상승하여 이격된 고정단자를 작동단자판의 가동접점이 자동으로 접속 연결되고, 상승된 작동봉을 인위적(수동)으로 눌러주면 상승된 작동지지관이 복귀판스프링의 탄발력에 의해 하향하면서 작동단자판을 하향시켜 고정단자의 접속을 인위적으로 차단시켜 주도록 된 반자동 리미트스위치를 제공하려는 것이다.To explain this in more detail, a pair of fixed terminals to which a signal (power) line is connected is fixedly installed inside the switch body covered with a cover, and an operation support tube having an operation terminal plate is provided between the fixed terminals. It is installed, but it is made by inserting the operating rod by drilling the distribution hole on the inner vertical line of the operation support tube.When the signal (power) is input to the fixed terminal, the operation terminal plate is raised together with the operation support tube into which the operation rod is inserted, so If the operating contact of the operating terminal plate is automatically connected and connected, press the raised operating rod artificially (manually) to lower the operating terminal plate while lowering the operating terminal plate by the elasticity of the return plate spring. It is to provide a semi-automatic limit switch that will artificially shut off the circuit.

통상적인 스위치 기능을 실시하도록 된 종래의 리미트스위치로서는 국내의 공개특허 공개번호 10-2005-62353호와 본인에 의해 제안된 특허 등록 제10-498227호 등이 알려져 있다.As a conventional limit switch to perform a normal switch function, Korean Patent Publication No. 10-2005-62353 and Patent Registration No. 10-498227 proposed by the person are known.

전자(공개특허 공개번호 10-2005-62353호: 리미트스위치)는, 본체의 내부에는 도전성 판스프링에 의해 탄발되는 가동자가 축으로 설치되어 있고, 본체의 외측 으로 돌출되는 가동자축에는 일단에 롤러가 굴대 설치된 레버가 장착되어 있으며, 본체의 내면 상단과 가동자의 일면에는 단자와 연결되는 가동접점과 고정접촉자가 각각 설치된 것으로서, 접촉수단(면)에 롤러가 접촉되면서 레버를 작동시키면 회동축이 회전하면서 가동접점을 고정접촉자에 접촉시켜 작동신호를 유통시켜 주도록 된 것이다.In the former (Public Publication No. 10-2005-62353: Limit switch), a mover is provided with a shaft that is elasticated by a conductive leaf spring inside the main body, and a roller is provided at one end of the movable shaft that protrudes out of the main body. A lever installed with a mandrel is installed, and a movable contact and a fixed contactor connected to a terminal are respectively installed at the upper end of the inner surface of the main body and the mover. When the lever is operated while the roller contacts the contact means (surface), the rotating shaft rotates. The movable contact is made to contact the fixed contactor to distribute the operation signal.

또 후자(특허 등록 제10-498227호: 승강기의 리미트스위치)는 전자를 개선한 것으로서, 본체의 내부에 입력단자와 출력단자를 분리 설치하고, 본체의 외부에 장착되는 탄성부재(코일스프링)에 의해 탄발 복귀되는 레버의 개폐단지지지편에는 Y자형개폐단자를 장착하며, 접촉수단(면)에 롤러가 접촉되면서 레버가 작동되면 레버의 개폐단지지편에 장착된 Y자형개폐단자가 본체의 내부에 분리 설치된 입력단자와 출력단자와 접속되면서 작동신호를 유통시켜 주도록 된 것이다.In addition, the latter (patent registration No. 10-498227: elevator limit switch) improves the former, and separately installs an input terminal and an output terminal inside the main body and attaches to an elastic member (coil spring) mounted outside of the main body. Y-shaped opening and closing terminal is mounted on the opening and closing terminal support piece of the lever which is returned by shot.When the lever is operated while the roller is in contact with the contact means (surface), the Y-shaped opening and closing terminal mounted on the opening and closing end support of the lever It is connected to the input terminal and the output terminal separately installed to distribute the operation signal.

그러나, 상기와 같이 구성되고 작동되는 종래의 리미트스위치(승강기의 리미트스위치)들은, 롤러가 접촉수단(면)에 접촉되면서 레버를 작동시켜 단자를 개폐단자가 고정단자에 접촉되어 작동신호가 유통되면 롤러가 접촉수단(면)을 완전히 벗어날 때까지는 레버를 인위적인 방법에 의해 작동시킬 수 없게 된다.However, the conventional limit switch (limit switch of the elevator) configured and operated as described above, when the roller is in contact with the contact means (surface) and the lever is operated to open and close the terminal to the fixed terminal and the operation signal flows. The lever cannot be operated by an artificial method until the roller is completely out of the contact means (face).

즉, 리미트스위치가 작동하여 엘리베이터와 같은 기계장치가 작동하게 되면 로러가 접촉수단(면)을 완전히 벗어날 때까지는 엘리베이터와 같은 기계장치를 작동 중에 인위적(수동)으로 정지시킬 수 없는 문제가 있고, 특히 기계장치를 작동시키는 도중에 안전사고 등의 비상사태에 의해 급히 정지시키고자 할 때에는 로러가 접촉수단(면)을 완전히 벗어날 때까지 정지시킬 수 없는 문제가 있다.That is, when the limit switch is operated to operate a mechanical device such as an elevator, there is a problem that the mechanical device such as an elevator cannot be stopped artificially (manually) during operation until the roller completely leaves the contact means (face). If you want to stop quickly by an emergency such as a safety accident during the operation of the mechanical device, there is a problem that can not be stopped until the roller is completely out of the contact means (surface).
