Snap Action, Limit Switches: WLG2-LES Application Field and Working Principle

Snap action limit switches are among the most important form of components used in automation procedures. There are various manufacturers who produce a wide range of snap-action limit switches such as the WLG2-LES series. These WLG2-LES limit switches are designed specifically for use in automation procedures, and are capable of continuous operation thanks to their robust design, and ease of modification in the field.

The WLG2-LES is a single-pole, single-throw (SPST) contact with a narrow operating gap and reliable repeatability for a variety of loads. It uses a different contacts configuration to most other switches of its class, using a dual contact configuration with a center spring that works at both ends. This design makes it more durable, easier to install, and more effective in its operation.

An Overview of the Application Field

The WLG2-LES series works particularly well in harsh operating environments or larger machines due to its combination of two large steels springs, which make it one of the most reliable limit switches in the market. It is also capable of accurately indicating the end of a moveable part while providing strong contact forces and reliable operation in a rugged environment. In addition, its low closing speed makes it a perfect fit for high cycle operations, such as assembly machinery, packaging and conveying machinery, flow control, and automotive applications.

Because of its robust design, the WLG2-LES series can tolerate extremes in temperatures and pressure, which make them ideal for applications in the food and beverage, pharmaceutical, manufacturing, and transportation industries. It is also used in robotics, automotives and HVAC systems, as well as other applications requiring reliable snap-action limit switches.

The Working Principle

The WLG2-LES limit switch is operated when the actuator moves between two electrode contacts. When the actuator moves, it applies pressure on one end and releases pressure on the other end. When the actuator reaches a certain position the contact is closed, which means the two surfaces of the actuator touch the two electrodes, creating an electrical circuit which triggers a switch.

The WLG2-LES limit switch is designed with a center spring that works at both ends, with the spring providing a powerful, repeatable action. This helps to ensure that the switch is reliable over many cycles, as the springs allow for a consistent operation each time.

The WLG2-LES limit switch is designed to be adjustable, so that the closed and open positions can be altered while the switch is mounted. This makes it easy to modify the switch to fit the needs of any application.

Conclusion

The WLG2-LES is an excellent limit switch for applications requiring a robust design, reliable, repeatability and adjustable operations. It can provide reliable and accurate operation in a wide range of applications, from high cycle machinery to harsh operating environments. It is also incredibly versatile, with its adjustable operations, making it suitable for a wide range of applications.
