83278029 Snap Action, Limit Switches Application Field and Working Principle

Snap action, limit switches are devices used extensively in factory automation and process control applications. These switches are devices that are activated when an object strikes a target, causing an electrical signal to be sent. Before discussing the application and working principle of 87278029 snap action, limit switches, it is important to understand what these switches are and why they are important to industrial automation and process control.

Definition and Overview

Snap action, limit switches are typically used to detect the presence or absence of an object, or to sense the position of an object. They can also be used to detect the rate of movement of an object. Snap action, limit switches work by detecting changes in the angular or linear position of a moving object, or the presence or absence of an object, via mechanical contact. When an object strikes the switch, it breaks a contact, generating an electrical signal. This signal can then be used to activate an electrical device, relay, or process.

Uses and Applications

Snap action, limit switches are used in a wide variety of applications in factory automation and process control. They can be used to detect the presence or absence of an object in a given area, the position of an object, or the rate of movement of an object. Additionally, they can be used to generate a signal if an object moves too fast or too slow.

These switches are commonly used in industrial production lines. They can be used to detect when a product has reached a certain point in the production line, or to detect if a product is out of specification. They can also be used to detect if a product is missing from the line, and to detect the speed of product movement.

Snap action, limit switches are also used in controlling automated processes. They can be used to detect when a process has reached a certain point, to detect if a process is in a correct or incorrect state, or to detect if a process is moving too fast or too slow.

Working Principle

The working principle of snap action, limit switches is based on a mechanical contact that is broken when an object strikes the switch. When the mechanical contact is broken, an electrical signal is generated, which can then be used to activate a relay, electrical device, or process. The amount of force applied to the switch determines the amount of signal that is generated, as well as how quickly the signal is generated.

Snap action, limit switches typically contain two contacts called a “make” and a “break”. The make contact is normally open, and the break contact is normally closed. When the switch is struck, the make contact breaks, which causes the signal to be generated. When the switch is released, the make contact is reset, which resets the signal.

These switches are typically designed to be actuated by a moving object, hence the name “snap action”. When the object reaches the switch, the contacts are quickly broken, which generates the signal. The amount of force required to actuate the switch can be adjusted, which allows the switch to be used in a wide variety of applications.

Conclusion

Snap action, limit switches are devices that are used extensively in factory automation and process control applications. They are activated when an object strikes the switch, causing an electrical signal to be sent. These switches are used to detect the presence or absence of an object, to sense the position of an object, or to detect the rate of movement of an object. The working principle of these switches is based on a mechanical contact that is broken when an object strikes the switch, which generates an electrical signal.
