Snap Action, Limit Switches

WLG2-55 is a highly reliable, long-life switch designed by Omron—a multinational electronic components manufacturer. It is a snap action, limit switch, which refers to a manual switch actuated though a mechanical actuator that exhibits elasticity that, when triggered, produces an audible click as the actuator snaps back to its original position. These switches are very useful in various applications, especially those that require rapid switching thanks to their snap action mechanism.

Application Field

WLG2-55 snap action limit switches are applied in a wide range of industrial applications, such as:

  • Door Interlocks and Door Position Safety Switches – WLG2-55 switch is typically used for door position safety switches as it provides accurate information about the respective door status. The switch also serves for safety latching purpose, meaning that the door automatically locks to a secure position when it is closed.
  • Emergency Stop Switches – Similarly, WLG2-55 limit switches are reliable and used for applications where the ability to quickly stop a process due to an emergency is required.
  • Limit Switches in Automation – WLG2-55 limit switch is often used in automation applications where a device needs to track a position. This type of switch allows the device to precisely determine the exact movements of a machine or a process and to react in visible and measurable manner.
  • Machine Workpiece Detection – WLG2-55 switch can also be used for part detection applications, such as a machine tool or part feeding application.

Working Principle

WLG2-55 snap action limit switch is an electrical contact switch with an automatic trigger. It is operated through elastic movement through a mechanical actuator, which is connected to the electrical contact system. The main purpose of the actuator is to switch the corresponding contact system from one open-circuit position to a closed-circuit position, which allows electrical current to flow through. When the actuator is triggered, the contact system opens and closes quickly, producing a loud and sharp sounds as it snaps back to its original position. The contact system consists of two parts: a shaped contact element, which carries two metal pieces arranged in a line and separated by a gap and held together by a metal spring, and a transfer contact which carries a single metal piece. The metal pieces that make up the shaped contact element carry electric current when they are connected together, while the metal piece of the transfer contact is a static element.

The transfer contact part of the contact system turns the static metal piece into a movable one when it is triggered by the actuator. As the actuator presses down, the static element of the transfer contact passes its force onto the metal pieces of shaped contact element, connecting them, thus allowing electric current to flow through. After the actuator is released, the metal pieces of shaped contact element are pushed back with a snap by the metal spring, which breaks the electric contact and stops current from flowing. This snap action mechanism is what makes the WLG2-55 snap action limit switch useful for applications such as door interlocks and emergency stops.

Conclusion

The WLG2-55 snap action limit switch from Omron is a highly reliable and long-life switch suitable for a variety of industrial applications. It is actuated by a mechanical actuator that produces an audible click as the actuator snaps back to its original position, providing rapid switching on and off of the electric current. The switch is composed of two parts: a shaped contact element containing two metal pieces separated by a gap and held together by a metal spring, and a transfer contact containing a single metal piece. When triggered, the transfer contact forces the static metal piece of the shaped contact element to connect and allow electric current through.
