Snap Action, Limit Switches Application Field and Working Principle

Snap action switches are a type of switch which are designed to react quickly and accurately to a predetermined criterion of operation. There are many different types of snap action switches available, and they are used in a variety of applications including home appliances, industrial machinery, medical equipment and more. In this article, we will look at the basic principles of snap action switches and explain their application field and working principle.

Application Field of Snap Action Switches

Snap action switches are widely used in many different applications. They can be found in home and industrial appliances, medical equipment, and even automobiles. They are generally used to detect when a certain condition is met such as when the water level has reached a certain level, or when a button has been pushed, or when a certain height has been reached. Some snap action switches also have an adjustable sensitivity so that they can be adjusted to fit the application at hand.

Snap action switches are also used in safety and security applications. They are often used to detect when a door or window has been opened or closed and can be used to trigger an alarm system or other security measures. They are also used to detect the temperature of a room or appliance, and can help ensure that safety guidelines are met.

Working Principle of Snap Action Switches

Snap action switches work by detecting a certain level of movement or force, causing a small metal piece to snap into place generating a change in the electrical current. This change can then be used to register when a certain condition has been met, or it can be used to switch on or off a circuit or appliance. The amount of movement, or force, required to trigger the switch can be adjusted by changing the tension of the contacts or changing the size of the contacts.

The most common type of snap action switch is the snap-action toggle switch. This type of switch is usually used to control the on/off function of electrical appliances, such as a light switch. The toggle switch acts like a lever, and when the lever is moved, a switch is tripped, which causes a change in the electrical current.

Snap action switches are also used in other applications such as in medical equipment. They can be used to monitor the flow of air, pressure sensors, and more. In some instances, they can even be used as a relay switch, which allows two different signals to be passed along in a circuit.

Conclusion

Snap action switches are a type of switch which are designed to react quickly and accurately to a predetermined criterion of operation. They are widely used in a variety of applications and are known for their reliability and accuracy. By understanding their working principle and application field, you can better understand how they can be used in different applications.
