The present invention relates to a limit switch including: a housing in which a first contact part is formed; a connector part which includes a second contact part combined with one end, a first bent part dividing a part of a body into a central part and a both-side part being formed so that the central part between the central part and the both-side part is bent from the end side to the upper side, a second bent part formed in the second contact part and formed to be bent to the upper side, a third bent part formed between the first bent part and the second bent part formed to be bent to the lower side, and a fourth bent part in which both-side part between the central part and the both-side part is formed to be bent to the upper side between the first bent part and the third bent part; a terminal which is combined with the bottom surface of the housing so that one end protrudes and which is positioned so that the one end is surrounded by the fourth bent part; a holder which is combined with the housing and which moves according to the external pressures; and a plunger which is inserted inside the holder and which moves together according to the movements of the holder in a contact with the upper surface of the connector. The limit switch, which is provided by the present invention, restricts or controls safely because the connector part and the terminal are always connected even in a bad situation like an excessive external pressure by forming the first bent part which is bent to the upper side in the connector part inside the housing and surrounding one end of the terminal in the first bent part. |
