Automatic limit switches are electrical components that serve many different functions. They are just one type in the field of Snap Action, Limit Switches. The LSU6B is one of these switches that you may come into contact with depending on the uses. In this article, we are going to discuss the application field as well as the working principle of the LSU6B Limit Switch.

Description

The LSU6B Limit Switch is an encased switch that is used to activate the electricity when its plunger is touched. It typically comes with a lever-operated armature, external contacts and an internals contact part. This contact part is manipulated by a sealed, rotary magnetic field.

The contact parts are suspended within the casing by a flexible support spring. This spring is taut when the device is deactivated but becomes slack once the plunger is touched. There are two separate contacts that represent either on or off.

Applications

The LSU6B Limit Switches can be used in numerous applications. Most commonly, it finds use in automotive and machinery. This switch can control the entire machinery or activate electrical systems like fans, pumps and motors.

The LSU6B is often used for security systems and anti-theft devices as well. This switch can be used to detect the movement of valuable equipment or items. It is relatively easy to set up and monitor from afar.

In addition, the limit switch can be used as a safety switch for machinery. It can detect any hazardous conditions or any risky positions before activating the emergency stop.

Working Principle

The LSU6B Limit Switch is operated by a magnetic field. When the plunger is not pressed, the contacts are separated, effectively deactivating the electrical circuit. When the plunger is pressed, the flexible support spring of the contact part should move, to compress the armature. Consequently, the external contacts will be brought together to complete the electrical circuit.

The magnetic field created by the rotating magnets is used to arouse the armature. With the energising, the armature is released and can move to the new position with the movement of the plunger. This position then determines whether the contacts are connected or not.

Conclusion

The LSU6B Limit Switch is a versatile, electrical component from the Snap Action, Limit Switches category. It is used for multiple applications and fulfils many roles such as electrical, security and safety devices. The working principle of the device is relatively straightforward and is presentable as a simple diagram. This makes it useful for many applications.
