Snap Action and Limit Switches are devices used extensively throughout industry to detect the state of mechanical parts, initiate circuit functions, indicate the presence of an object, or to alert when something goes wrong. XE-QA2-2 is one such product, using snap-action contacts to give reliable and precise switching actions. This article will look at the application field and working principle of the XE-QA2-2.

Application Field

XE-QA2-2 is a micro switch for various different applications and has several features that make it a popular choice for those within the industry. This includes its resistance to high impact forces and its ability to work in high temperatures (up to +85°C). XE-QA2-2 is also resistant to ambient vibration and delivers a high electrical performance, ensuring that the switch remains reliable, precise and accurate in operation.

XE-QA2-2 can be used in many environments and applications, such as: automotive, telecommunications, automotive and home appliance. It is also used in industrial robotics and automated systems, where its precise and reliable switching action is a huge advantage.

Working Principle

The XE-QA2-2 is a snap action, limit switch which is operated by a lever and linkage. This means that the contact arms move at a fast rate and open or close the contacts quickly when triggered. This snap action mechanism helps provide accurate switching and instant response time, even in high temperature environments.

The operating performance of the switch depends on the snap action mechanism, the lever movement and spring loading of the contact arms. The contact arms are held in place by a spring, which helps to keep the arms in place and provide consistent switching performance. When the lever is moved and the contact arms are pushed over, the force of the spring helps to return the arms to their original position when the lever is released, allowing the contacts to close again.

The design of the XE-QA2-2 also helps to simplify assembly and promote durability. It is designed with both snap-action and non-snap-action options, making it easier to identify which type of switch is the best fit for the application. The design also allows for a longer life and improved reliability, ensuring that the switch will endure a long period of use and still maintain accuracy.

Conclusion

XE-QA2-2 is a snap-action, limit switch which is often used for various different applications due to its reliable and precise switching action. It has a high temperature resistance of up to +85°C and is suitable for use in the automotive, telecommunications, automotive and home appliance industries. Its snap-action mechanism, lever movement and spring loading of the contact arms make it reliable and accurate, while its design simplifies assembly and promotes durability, making it a popular choice in industry.
