WLF2D

The WLF2D snap action limit switch is an industrial automation device that provides a regulated mechanical operation with an adjustable range of motion. This type of device is typically used as part of a control system to control the flow of air and water, or to indicate the level of a liquid or gaseous material. They are often found in the process control and instrumentation applications.

The primary purpose of a WLF2D snap action limit switch is to provide flexibility to an existing control system. By varying the adjustments of the switch, operators can tailor the system to their specific needs. For instance, if the process requires additional safety measures, the WLF2D switch can be adjusted to open or close the system at any point within its pre-determined range.

The primary components of a WLF2D snap action limit switch are its housing, actuator disc, lever, roller mechanism, and arcing rod. The housing encompasses the other components and provides an anchor point for the other components of the switch. The actuator disc, which is mounted on the outside of the housing, is connected to a lever. The lever is used to control the switch by pressing or releasing it. The roller mechanism is used to carry the disc and lever, as well as to allow for movement of the leverage without moving the actuator disc.

The WLF2D snap action limit switch works by using a mechanical lever to move the disc between two states. When the lever is pressed down, the disc turns clockwise and when it is released, the disc turns counter-clockwise. The arc rod connects the disc to the roller, allowing it to turn when the lever is released. The roller then carries the disc up or down, depending on the direction it is being turned. By adjusting the rod, the distance between the disc and the opening of the switch can be altered.

The WLF2D snap action limit switch is reliable and durable, and is often preferred over other switch types due to its simplicity and versatility. It is able to respond to a wide range of control signals, and can also be easily adjusted to be used in different control systems. This limit switch is a viable option for many industrial applications, and can provide a valuable performance boost in a process or instrumentation control system.
