Rocker switches are found in a diverse range of scenarios, from controlling small appliances in the home to handling multi-million-pound industrial plant. One of the most popular members of the rocker switch family is the LW3122-N4CE-A switch. This article will look at this particular switch’s applications in greater detail, as well as its working principle.

The LW3122-N4CE-A switch is most commonly used in industrial and commercial applications. For example, it can be used to provide convenient control over motors, actuators and electronic circuits. Its versatility and tough construction make it ideal for many demanding, continuous-use environments. It is also a popular choice in public facilities such as leisure centers—the robust construction helps to ensure reliable operation over an extended lifespan.

The switch is designed around a simple mechanism. The body of the switch is formed from a single injection-molded component, usually constructed from thermoplastic or glass-filled polycarbonate. The two contact terminals are fitted within the upper and lower portions of the component in addition to a pair of conductive contact pads within the middle. A pair of robust, spring-loaded rockers is fitted to the component on the outside, providing simple and tactile control over the contact pads.

Connections are made to the respective contact pads, which are then protected by a sturdy button cap. The button cap serves to protect the contacts from dirt, dust and other extraneous matter, thereby increasing the switch’s resistance to premature failure. To complete the assembly process, the rockers can be fitted either with a colored plastic actuator or a metal flag. This helps the switch to fit in with any design aesthetic.

When using the switch, the rockers pivot around the point where the upper and lower contact pads meet. When a rocker is pushed inwards it moves the associated pad sideways, causing a bridge to form between the two contact points. This bridge represents a closed circuit which allows a current to flow and complete the desired operation. Releasing the push retention feature then triggers reset, restoring the switch to its original, open state.

The simplicity of the mechanism combined with the robust design makes this switch perfectly suited for the majority of industrial and commercial applications. The long-term durability of the LW3122-N4CE-A switch helps to reduce down time and improve profitability in any industrial environment. Its wide range of uses make it an excellent choice for a range of scenarios, and its reliable operation ensures it can be relied on in even the most difficult of conditions.
