Rocker Switches

U211J3WQE2 is a type of rocker switch that is often used in low voltage applications such as in car audio systems, electric door locks, and lighting systems. It is a two-position, single-pole switch with an actuator that is usually formed from a synthetic resin. The switch has up to three terminals for connecting terminals and typically uses a one-way actuation.

Application Field

The U211J3WQE2 rocker switch is primarily used for low voltage applications and can be used to control any device that requires a toggle switch arrangement. It is most commonly found in car audio systems, such as radios and amplifiers, electric door locks, as well as small lighting fixtures, such as ceiling fans and cabinet lighting. It can also be used as part of connecting complex control systems, such as HVAC and alarm systems. Rocker switches are sometimes used as a substitute for membrane switches, which often have higher wear characteristics. They are available in a variety of sizes and styles to meet the needs of the device.

Working Principle

Rocker switches are typically momentary, meaning they will only remain in the activated position until the actuator is released. When the actuator is pushed in, an internal connection is made to a common terminal. A return spring may be incorporated, which will restore the switch to its original position when the actuator is released. The common terminal is connected to two other conductive terminals which are usually designated as \'On\' and \'Off\'. Depending on which position the switch is in, electrical current will be allowed to flow through one terminal, while the other is open.

The U211J3WQE2 rocker switch allows for creative control options and is used in an extensive range of applications. The materials used in the construction of the switch such as metals and insulators make them extremely durable and able to handle high volumes of electrical current. They are widely available and can be found in almost any hardware store.
