Limit Switches

A limit switch is an electromechanical device used in various industrial applications to control the movement of machinery. It plays a crucial role in ensuring safe and reliable operation by limiting the travel of an object to a certain point.

A typical limit switch consists of a switch body, an actuator mechanically linked to an operating lever, and electrical contacts. When an object contacts the actuator, it causes the operating lever to move, which in turn activates the switch. This process may involve various configurations of actuators, including plungers or rollers.

The switch actuator movement causes a change in the electrical connection within the switch. The electrical contacts, often present in an open or closed circuit configuration, change state when the switch is actuated. If the contacts were in an open state, the circuit is closed (and vice versa) when the switch is triggered.

Limit switches are typically connected to a control system. When the switch changes its state, it sends a signal to the control system to either start or stop a process. For instance, in a conveyor belt system, a limit switch may signal the system to stop the conveyor when it detects that an object has reached the end of the line.
