Snap Action, Limit Switches are widely used in a variety of automation applications. These devices sense measurable physical variables such as temperature, pressure, force, or electrical current, and provide a digital output indicating whether a particular limit has been exceeded. The WLG2-G1LD snap action limit switch is a single-pole, double-throw (SPDT) normally open and normally closed contact switch. This device can detect motion or vibration and then convert it into a digital output signal.

Working Principle

The WLG2-G1LD snap action limit switch works on a simple principle. An actuator, such as a roller, lever, or plunger, is attached to the switch. When a certain amount of force is applied to the actuator, the contacts inside the switch are released or engaged, allowing or blocking the flow of electricity. This is known as snap action.

In the normal condition (when no force is applied), the contacts are separated and the switch is open. When the force is increased, a point is reached when the contacts snap together and the switch is closed. This is known as the switching point. The same principle is used in latches, locks, and other mechanical components.

Application Fields

The WLG2-G1LD snap action limit switch is most common in industrial automation, such as on automated assembly lines. It is used to detect the end of a path in robotic arms, and to stop the process when a predetermined limit is reached. It is used in safety circuits to stop potentially dangerous machinery in the event of an unexpected anomaly or external force. It can also be used in domestic applications to activate lights, appliances, and other electrical components.

The WLG2-G1LD is also used in medical equipment. In infusion pumps, for example, the limit switch is used to detect when the plunger has reached the end of its travel. This helps to prevent overfill of the fluid, and is essential for accurate dosages. The WLG2-G1LD is also used to detect the position of patient beds, wheelchairs, and other items of equipment in hospitals.

The device is also used in the automotive industry. It can be used to activate seat belt warning systems in cars, as well as a variety of other functions. It is also used in aircraft to monitor flaps and other components for proper functioning.

Advantages of Snap Action, Limit Switches

Snap action, limit switches offer several advantages over other types of switches. They are reliable and have a long operating life. They also offer precise accuracy, with a well-defined switching point. This helps to prevent false trips and/or inaccurate readings. The WLG2-G1LD model is also extremely durable and resistant to damage, making it a popular choice for a variety of applications.

Conclusion

The WLG2-G1LD snap action limit switch is a highly useful and reliable device with numerous applications in the automation, medical, and automotive industries. Its snap action principle is simple yet effective, providing accurate results with each switch. Its durability and long operating life make it an ideal choice for a variety of applications.
