Rocker Switches

Rocker switches are electrical switches which are operated by a small lever, known as a rocker, which is usually large enough to be pushed with the fingers. These switches are most commonly used as on/off switches, but they can also be used as dimmers, or be combined with other switches to control additional functions such as fan speed, power level, and motor speed.

U21J1AQE2 Application Field

U21J1AQE2 switches are widely used in a variety of industries, including automotive, aviation, marine, and medical. They are also popular in commercial and residential buildings, as they are easy to use and provide an efficient method of switching electrical loads between different circuits. The switches are also available in a variety of voltage ratings, and are designed to be used in wet, damp, and corrosive environments.

U21J1AQE2 Working Principle

The working principle of the U21J1AQE2 switch is simple. When the lever is pushed, the switch closes, providing a path for electrical current to flow. When the lever is released, the switch opens, breaking the connection and cutting off the flow of electricity. This type of switch is typically illuminated, and the light serves as a visual indication of whether the switch is on or off.

In addition to being capable of controlling the flow of electricity, U21J1AQE2 switches also come with a variety of safety features. They are designed to shut off the power if a short circuit or overload is detected. This type of switch also features a lockout feature which prevents unauthorized users from accessing the switch, and a ground fault circuit interrupter (GFCI) which stops the flow of electricity if a short circuit is detected.

Conclusion

Rocker switches are a reliable and efficient way to control electrical loads in a variety of applications. The U21J1AQE2 switch is a popular choice due to its robustness and versatility. It is available in a variety of voltage ratings and is designed to work in wet, damp, and corrosive environments. The switch is also illuminated, and it offers additional safety features such as a lockout and GFCI to help protect against potential hazards.
