What is a Limit Switch?
Limit switches are switches that are activated by the movement of machine parts or the presence of objects.
As part of a control system, they are used to detect safety interlocks or objects passing through a specific position to automatically start or stop a machine, limit the range of motion of a machine, or detect its position.
Limit switches have a microswitch built into a metal or plastic enclosed case to protect it from external forces (ex. water, oil, gases, dust, etc.) in the operating environment. The contact is turned on or off by the movement of an actuator (mechanical sensing part).
Actuators include plunger type (direct-acting type), rotary lever, fork-lock lever, flexible rod, etc., and are available in a variety of shapes according to the application and operating environment.
Applications of Limit Switches
The use of limit switches is to turn on or off an electric circuit as a result of detecting the position of an object.
In automation systems for automatic control of factory production lines and the like, limit switches are used to detect the movement and position of machines. For example, a limit switch is installed at a detection position and turns on at an abnormal operating position, triggering an alarm and stopping machine operation.
Another familiar example is an elevator cage (a conveyor that carries people and luggage up and down). When the cage reaches a predetermined position on the floor where it stops, the limit switch activates to stop the motor and the cage comes to a stop.
Thus, limit switches are used in a variety of applications in automatic control systems.
