What is limit switch in motor control?
In electrical engineering, a limit switch is a switch operated by the motion of a machine part or the presence of an object. A limit switch can be used for controlling machinery as part of a control system, as a safety interlock, or as a counter enumerating objects passing a point.
How limit switches are used in motor control applications?
The limit switch then regulates the electrical circuit that controls the machine and its moving parts. These switches can be used as pilot devices for magnetic starter control circuits, allowing them to start, stop, slow down, or accelerate the functions of an electric motor.
What is the function of limit switch in control valve?
The limit switch supplies a limit signal when an adjusted limit value is exceeded in either direction, especially when a control valve has reached a final position. This signal is suitable for reversing control signals, initiating visual or audible alarms and for connection to central control or alarm systems.
