Snap Action, Limit Switches: WLG2-G1-N Application Field and Working Principle

A limit switch is a switch that is used to detect the presence of an object by using mechanical operation to open or close an electrical circuit. Generally, a limit switch consists of an actuator and a switch element. The actuator is the part of the switch which makes contact with an object, and the switch element is a contact, normally open, which opens or closes when an actuator is operated.

WLG2-G1-N is a series of snap action limit switches from the brand Simatic. These switches are available in either a normally-open or normally-closed configuration, and they provide a high degree of accuracy, reliability, and good contact-closure characteristics. The typical life span of the switches is 50 million cycles.

The WLG2-G1-N limit switches are mainly used in industrial automation applications such as conveyors, packaging machines, process lines, closing circuits on water flow and over temperature conditions, and many other applications where reliable mechanical and electrical contacts are required.

The WLG2-G1-N switch works off of a mechanical principle that is known as a snap action switch. A snap action switch is characterized by a momentary actuation of the switch followed by a quick return to its original state when the switch is released. This type of switch is useful for a variety of applications because it can respond rapidly to a change in physical condition.

The WLG2-G1-N snap action limit switch utilizes a spring-loaded plunger that is activated by a physical force (mechanical, electrical, or magnetic). When a sufficient force is applied, the plunger is forced against a contact, which in turn causes a change in the electrical state of the circuit. When the switch is released, the spring quickly returns the plunger to its pre-activated position, resetting the switch to its original state.

The WLG2-G1-N limit switch is also equipped with a variety of features that improve its performance and reliability in many applications. For instance, the switch has a corrosion-resistant housing and contacts, a variety of mounting options, interchangeable actuators, and a choice of activation forces. Additionally, it has a low current rating, which makes it suitable for a variety of industrial applications.

Overall, the WLG2-G1-N limit switch is a very reliable and versatile switch that provides accurate, reliable contact closure and can operate in demanding industrial conditions. The switch’s snap-action mechanism also makes it suitable for many applications where fast response times are needed. Moreover, its versatile features make it well-suited for many types of industrial automation applications.
