Rocker switches are a type of switches which are widely used across a number of different applications, particularly in the consumer electronics industry. U21J3V7QE1 is a type of rocker switch which is specifically designed for use in consumer electronics and home appliance applications. In this article, we will look at the application field and working principle of this type of rocker switch.

Firstly, let us look at the application field of U21J3V7QE1 rocker switches. These types of switches are typically used to control the turning on or off of electrical or electronic devices. The switches can be used in applications such as TVs, home theater systems, game consoles, and home appliances. They are also often used in industrial applications such as controlling motors, pumps, and ventilation systems. The U21J3V7QE1 rocker switches are particularly suitable for these types of applications as they are very rugged and durable, and have a long life span.

Now, let us look at the working principle of U21J3V7QE1 rocker switches. The switches are actuated by pushing or rocking the switch lever in the desired direction, which causes the switch contacts to close or open. The force required to actuate the switch is usually low, and can usually be adjusted to suit the particular application. The switches are usually manufactured from high quality materials such as brass or stainless steel, and are designed to withstand high levels of mechanical and electrical stress.

The U21J3V7QE1 rocker switches are designed to work in a number of different ways. They can be wired for normally open, normally closed, or energized open modes. In the normally open mode, the switch contacts open when the lever is pushed or rocked in the desired direction, and close when the lever is released. In the normally closed mode, the switch contacts are closed when the lever is pushed or rocked in the desired direction, and open when the lever is released. In the energized open mode, the switch contacts open when the lever is pushed or rocked in the desired direction, and remain open until the lever is released. The U21J3V7QE1 rocker switches also feature a built in overload protection, which prevents contact arcing or short-circuits.

The U21J3V7QE1 rocker switches are also designed to operate in an environmentally friendly manner, as they are RoHS compliant. This means that they are lead-free and do not contain hazardous substances. The switches are also UL-certified and comply with international safety standards.

In summary, U21J3V7QE1 rocker switches are a rugged and reliable type of switch which can be used in a wide range of applications, including consumer electronics and home appliance applications. The switches are actuated by pushing or rocking the lever in the desired direction, and feature built-in overload protection and RoHS compliance, as well as UL-certification. The switches can be wired for normally open, normally closed, and energized open modes.
