Rocker switches are electromechanical devices used to adjust certain electrical parameters. The most common uses of rocker switches are to switch between different items such as lights and fans, or between power supply and motor control. The U21J21ZQE22 is a rocker switch which is used mainly in industrial and military applications. In this article, we will look at the application field and working principle of the U21J21ZQE22 rocker switch.

Application Field

The U21J21ZQE22 is mainly used in industrial and military applications. It has a wide variety of uses, such as controlling electrical motors, air or hydraulic cylinders, or controlling temperatures. It is also used in high-voltage applications where a protected switch is desirable. This switch is also capable of carrying higher current loads than its competitors, which makes it ideal for applications where high-current power is needed.

Working Principle

The working principle of the U21J21ZQE22 rocker switch is relatively simple. The switch is actuated by a mechanical switch actuator, which is attached to the circuit board. When the actuator is pressed, it pushes the contacts together, which causes the switch to change state. When the actuator is released, the contacts open, and the switch returns to its original position.

The switch also has a torsional latching system which prevents accidental changes between the different positions. This makes the switch more reliable, as it is difficult to accidentally move the switch out of position. The switch also has a reverse action feature, which means that the contacts can be opened even when the switch is in the closed position.

The U21J21ZQE22 rocker switch is also equipped with a variety of safety features. It has a high inrush current capability, as well as an internal temperature limiter to protect against overheating. The switch also has protection from dust and dirt, and is rated for outdoor use.

Conclusion

The U21J21ZQE22 rocker switch is a versatile and reliable switch which is designed for use in industrial and military applications. It is capable of carrying higher current loads than its competitors, and is equipped with a range of safety features. The switch is actuated by a mechanical switch actuator, and has a torsional latching system to prevent accidental changes.
