Rocker switches are a type of electrical switching device that are typically used in a wide range of applications in the construction and control of electrical systems. The U18J21ZQE22 is one such rocker switch that is used in a variety of different applications.

The U18J21ZQE22 rocker switch is a general-purpose switch that is commonly found in a wide range of industrial applications. It is rated to handle up to 24 VDC or 6.3 Amp with a rated switching power of up to 8.4 W. Its design consists of a uniform plastic body with two terminal contacts and two rocking levers. The design of the U18J21ZQE22 typically allows for a snap-in mounting to help secure the switch in its designated position.

The U18J21ZQE22 rocker switch is typically used for applications such as machine control, lighting control, and electrical power switching. It is designed to withstand harsh environmental conditions and is UL approved, making it suitable for commercial and industrial applications. The switch can also be used in medical equipment, vending machines, telecommunications, and home appliances.

The working principle of the U18J21ZQE22 rocker switch is simple. When the lever is pushed in a downward direction, the ON terminal of the switch is closed. At the same time, the OFF terminal opens, thereby preventing current from flowing through the switch. When the lever is in its original position, the OFF terminal is closed and the ON terminal is open. This prevents current from continuing to flow through the switch, allowing for an efficient on/off switching of electrical devices connected to the switch.

In conclusion, the U18J21ZQE22 is a type of rocker switch that is used for a variety of applications in the control of electrical systems. Its snap-in mounting design allows for secure mounting and its built-in protective features make it suitable for commercial and industrial applications. Additionally, the working principle of the U18J21ZQE22 is simple and efficient, allowing for convenient on/off switching of associated electrical devices.
