LW3123-N4BB-H

Rocker switches are a type of mechanical switch that are characterized by their “rocker” mechanism, meaning two often-contrasting parts of the switch body slide together to “rock” back and forth, creating a “click” when pressed. The LW3123-N4BB-H, a rocker switch produced by Littelfuse, is a single pole, double throw, normally open switch and is rated for 6A-125VAC, 3A-250VAC, or 0.2A/12VDC at both terminals.

For applications where safety is paramount, such as medical equipment or industrial machinery, the LW3123-N4BB-H is DC rated with a higher voltage and current rating than many other rocker switches. This effectively allows electricians and engineers to add additional control to their equipment in safer environments, reducing the likelihood of potential faults and hazards.

The working principle of the LW3123-N4BB-H is straightforward yet efficient. At its most basic, a rocker switch is a momentary switch between two electrical contacts. When the rocker is pressed, it rocks back and forth and snaps into place, creating a “click” sound. Additionally, the mechanism is engineered so that the actuation force required to activate the switch is always above the minimum required by law, and the button spring is crafted to provide the ideal tactile feedback when the rocker is pressed.

The LW3123-N4BB-H rocker switch also comes in both illuminated and non-illuminated models, and is available in various actuator designs, including push-button and paddle. The switch is typically used in consumer electronics, automotive and industrial applications, as well as in electrical control panels, modems and telecom equipment.

Due to its superior performance, ease of use and high-quality construction, the LW3123-N4BB-H rocker switch is a popular choice with engineers and technicians alike. Offering considerable advantages over standard push-button and toggle switches, such as higher current ratings, superior durability, tactile feedback, and lower operating forces, the LW3123-N4BB-H is an ideal choice for a variety of applications.
