PURPOSE: A limit switch is provided to sense the operation range of an operation lever by measuring the rotation angle of a rotary rod through a lever position sensing unit. CONSTITUTION: A limit switch comprises a housing, an operation lever(120), a lever position sensing unit. A switch unit(200) having a push button is installed in the housing. The operation lever is formed on one side of the housing and senses an object. A push rod is formed between a cam, formed on one end of a rotary rod connected to the operation lever, and the push button of the switch unit. The lever position sensing unit measures the rotation angle of the rotary rod to sense the operation range of the operation lever.
