Snap Action, Limit Switches 
The WLCA12-2NLD-DK1EJ03 switch is a snap action, limit switch. A limit switch is an electromechanical device used for making or breaking an electrical connection when a certain limit has been reached or gone beyond and, in this case, the snap action is triggered when a moving object, such as a lever, plunger, cam or other part, reaches the switch’s mechanical set point. The switch can be triggered in either a normally open or normally closed configuration, depending on the application.
Application Field 
The WLCA12-2NLD-DK1EJ03 is a multipurpose switch, therefore it is suitable for a wide range of applications. Commonly, these switches are used for industrial motion control, such as conveyors and material handling systems. Automation processes, circuit control and switchgear applications, including those for horticultural and special vehicle control, can also make use of this device. It is also a great fit for laboratory and hazardous area protection. The WLCA12-2NLD-DK1EJ03 offers many safety and reliability features as well as resistance to shock vibration, making it a versatile choice for many applications.
Working Principle 
When the moving part of the switch comes into contact with the mechanical setpoint of the device, the switch is triggered to break or make an electrical connection. In the WLCA12-2NLD-DK1EJ03 model, the mechanical setpoint is reached gradually, allowing for a smooth transition in the operations of the switch. This gradual breaking of the electrical connection reduces the risk of damage or downtime caused by long current spikes as the switch opens or closes.
The WLCA12-2NLD-DK1EJ03 features a ‘snap action’ design, meaning that once the moving part of the switch interacts with the mechanical setpoint, it is triggered with a quick action. This snap action creates a precise and precise break of the electrical connection, without any delay in the switch’s operation. In addition to the snap action, the switch also contains what is called a ‘quick-connect’ feature, allowing for easy installation of the device without extensive disconnection or installation of wires and terminals.
Conclusion 
The WLCA12-2NLD-DK1EJ03 snap action, limit switch is an effective and reliable device for many applications requiring precise motion and electrical control. The device is fast-acting, requiring little maintenance and installation, and is resistant to shock, vibration, and hazardous areas. The working principle of the switch provides quick and precise action, increasing speed and reliability, while the quick-connect feature allows fast and easy installation.
