Rocker Switches

Rocker switches are usually bistable tactile switches. They feature two or more mechanical rocker positions constructed out of a bendable plastic material. The switch can periodically switch between on and off state based on the rocking motion of the rocker arm. The rocker switch is designed to provide a visual indication of the current switch state.

LW3122-F4FC-A

The LW3122-F4FC-A is a 2 position rocker switch which features a twist-lock mechanism. It is designed for a wide range of application areas such as medical and industrial equipment. This rocker switch is rated for a very high current and voltage, up to 20A at 120V. The LW3122-F4FC-A is UL, CSA and VDE approved, and thus is suitable for a variety of industrial and domestic applications.

Application Field

Due to its high current and voltage rating, the LW3122-F4FC-A is ideal for controlling heavy-duty equipment. It is often used in automation control systems, power distribution systems and industrial lighting, where current and voltage ratings above normal limits are required. It can also be used in a range of consumer applications such as home appliances, gaming systems and audio amplifiers.

Working Principle

To understand the working principle of the LW3122-F4FC-A rocker switch, one must understand the arrangement of its internal components. Inside the rocker switch, a pair of normally closed metallic contacts are separated by a plastic base. When the switch arm is pressed, it causes the two contacts to separate and thus break the connection. By turning the rocker switch in the opposite direction, the two contacts are again brought in contact to form an electrical connection.

In addition to the metallic contacts, the LW3122-F4FC-A also features a twist-lock mechanism. When the switch arm is twisted, the lock automatically locks the switch arm in place to prevent any unintentional contact with the internal components. This lock provides an extra level of safety and helps prevent unexpected power outages.

Conclusion

The LW3122-F4FC-A is a high voltage/high current rocker switch designed for a wide range of industrial and domestic applications. It features a twist-lock mechanism, which makes it a safe and reliable choice for heavy-duty equipment. The switch arm needs to be twisted to create or break the connection, and a locking mechanism ensures that the arm is securely held in place.
