TFECV3VA155BC Application Field and Working Principle

TFECV3VA155BC is a micro-operation switch with snap action contact, which is widely used in the automation and control system to detect and adjust the object position. This switch has a wide range of applications and working principles which have become essential components for a variety of electrical systems.

Application Field of TFECV3VA155BC

TFECV3VA155BC are used for various types of applications as it offers reliable performance and long lasting service. It is mainly used in industrial automation, food and beverage, energy and lighting industries, security systems, medical and pharmaceutical applications, aerospace and defense, automotive, marine and control engineering industry. These applications generally involve controlling, monitoring and adjusting the position of an object in a secure and efficient manner.

Apart from these, the TFECV3VA155BC is also used in agricultural applications such as green houses, ovens, motor controls and agricultural machinery due to the stability and repeatability of the switch.

Working Principle of TFECV3VA155BC

The main function of the TFECV3VA155BC is to detect and adjust the position of an object. This is achieved by using a snap action contact that is actuated when the object’s position is changed. The snap action feature ensures that a consistent and reliable switching experience is guaranteed throughout its life span. The micro switch is then connected to an electrical system for further controlling or monitoring of the object.

The mechanical structure of the TFECV3VA155BC includes a plunger, a contact arm and an auxiliary spring. The plunger acts as the activation axis of the switch and pushes the contact arm when it is displaced by an object. This causes the contact arm to move over the auxiliary spring and torsion the contact. The torsion-spring ensures consistent performance up until the switch has released the contact.

Once the object has returned to its original position, the plunger will release the contact arm and reset the switch back to its starting position. This means that the switch is ready to be actuated again when the object’s position changes.

Conclusion

TFECV3VA155BC snap action limit switches are used in a variety of applications across different industries. The working principle of the switch is based on a mechanical design that actuates a torsion-spring contact that is connected to an electrical system. The reliable performance and repeatability of this switch make it ideal for a wide range of applications including industrial automation, energy and lighting, medical and pharmaceutical as well as agricultural applications.
