A limit switch is an electro-mechanical device that is commonly used to send electrical signals based on the movement position of an object or machine in various mechanical and automatic systems, thereby allowing the system to take the desired action.
This device is also known as a limit switch, micro switch, or basic switch. On the Limit Switch, there is an actuator lever that has the function of changing the position of the terminal contact. For example, from Normally Open (NO) to Close or vice versa, namely Normally Close (NC) to Open.
The way this device works is that when an object reaches a specified point, the switch contact will change position; it can become open or closed. It will then send a signal to the controlling device to perform a specific action.
With this way of working, the Limit Switch can play a role in controlling the movement of the machine being used, stopping operation when it reaches a certain limit, and triggering safety measures, such as the machine turning off automatically when the door is opened. This vital function can ensure safer operations in a variety of industrial environments.
