Product Description

what is limit switch box

A limit switch box is a device that is used to detect the position of a moving object. It is typically used in industrial settings to control the movement of machinery and equipment. The limit switch box consists of a housing, a switch, and a lever. The housing is typically made of metal or plastic and protects the switch from damage. The switch is typically a reed switch or a microswitch and is used to detect the position of the lever. The lever is typically made of metal or plastic and is attached to the moving object. When the moving object reaches a predetermined position, the lever will move and activate the switch. The switch will then send a signal to a control system, which will then take the appropriate action.
