Limit Switches
Limit switches are devices triggered by movement or the presence of an object, commonly used as part of machines. They play a vital role in control systems for a variety of equipment, such as doors, ice makers, and car elevators. Their widespread use is due to their ability to perform reliably under extreme conditions, simple installation, and overall dependability.
A typical limit switch includes an actuator, housing, an internal switch mechanism, and a protective switch enclosure. When the actuator detects motion or an object, it activates the switch, which then controls the electrical circuit.
Moujen offer an extensive range of limit switches in different shapes and sizes, including fully customizable options. These switches are designed for easy installation, cost-effective assembly, and high performance. They come certified with UL, CSA, and CE approvals to ensure quality and safety.
