WLG2-55LDK43

Snap action limit switches, also known as snap-action switches, are mechanical devices that make or break an electrical connection in response to a mechanical force.

The WLG2-55LDK43 snap action switch is a reliable and long-lasting electronic switch designed for industrial applications. It is a double-pole, single-throw (DPST) switch with a maximum operating voltage of 250 VAC and a maximum current of 16 A. The switch is constructed with a rugged plastic housing, gold-plated contacts, and snap action levers. The design of this snap action switch offers reliable, repeatable operations and smooth responsiveness.

Working Principle

The WLG2-55LDK43 snap action switch operates according to the principle of a snap action mechanism. As the name suggests, the switch uses a mechanism that releases a spring-loaded lever when it is triggered by an actuation force. When the actuator is pressed, the spring is released and the lever snaps to the open position. At the same time, the gold-plated contacts open, breaking the electrical circuit and preventing current from passing through. When the actuator is released, the spring returns to its original position and the lever snaps back to the closed position. The contacts then connect, allowing current to flow through the switch.

The snap action switch requires very little actuation force and has a proven track record of reliable, repeatable operations. It is also very quick to respond and is ideal for use in applications where fast, reliable switching is required.

Applications

The WLG2-55LDK43 snap action switch is commonly used in industrial applications, such as control and automation circuits, machine control, and safety systems. It is also used in other applications that require a rugged, reliable, and repeatable switch, such as in automotive, medical, and consumer products. The switch is capable of switching loads up to 16A and is certified to UL and CSA standards.

The WLG2-55LDK43 snap action switch is an excellent choice for many applications. Its robust design, reliable operation, and fast response make it the perfect choice for a variety of applications.
