Rocker switches are a type of switch that are characterised by a toggle rocker placed between two terminals. The LW3123-K4EE-B switch belongs to this family, and is commonly used in applications such as automotive, communications and industrial. This article will discuss the LW3123-K4EE-B switch and the typical applications in which it is used, as well as explain the working principle of the switch.

Application of LW3123-K4EE-B

The LW3123-K4EE-B is a 20A (maximum) double pole double throw (DPDT) on/off/on rocker switch. This type of rocker switch is used in numerous applications, ranging from automotive and communication applications to medical and industrial applications. Automotive applications are the most common, with the LW3123-K4EE-B being used to control headlamps, spotlights, battery packs and other lighting components on cars and boats. In communications, the LW3123-K4EE-B is generally installed on mobile and satellite communication devices, for switching between bands, channels and networks. In the medical field, it is used to control medical devices such as an oxygen supply, chest drainage systems and ventilators. In industrial applications, the LW3123-K4EE-B is employed to operate production line machinery, pumps, conveyors and other industrial equipment.

Working Principle of Rocker Switches

The basic principle of operation for all rocker switches is the same. The switch consists of a rocker arm, two sets of electrical contacts, and a spring-loaded actuator. The operation is straightforward. When the actuator is pressed, the rocker arm moves, which causes one set of contacts to be connected and the other set to be disconnected. The rocker arm then stays in that position, until the actuator is pressed again, or the switch is switched off.

The LW3123-K4EE-B rocker switch is equipped with a special double-pole / double-throw mechanism that allows for two separate circuits to be connected and disconnected. This is achieved by having four contacts, two for each circuit, arranged on the rocker switch. When the rocker switch is switched to the "on" position, the two circuits are connected, and when the rocker switch is in the "off" position, both circuits are disconnected. In addition, the rocker switch allows for two different circuits to be connected and disconnected simultaneously, allowing for a greater number of applications compared to other rocker switches.

Conclusion

The LW3123-K4EE-B rocker switch is used in a variety of applications, ranging from automotive and communications, to medical and industrial. One of its main advantages is its double-pole / double-throw operation, which allows for two separate circuits to be connected and disconnected simultaneously, making it ideal for more complex applications. The basic principle of operation for all rocker switches is the same, as the rocker arm is simply moved by an actuator to either connect or disconnect one or two sets of contacts.
