Snap Action, Limit Switches: WLG12-P1 Application Field and Working Principle

Snap action, limit switches, such as the WLG12-P1, are mechanical switches with two moving armatures and a stationary contact. They are designed with a flexible motion path that allows them to automatically switch between open circuit (off) and closed circuit (on) depending on the action of the armature. The advantage of their adjustable and consistent operation range makes them ideal for applications where precision and repeatability are essential.The application field for the WLG12-P1 and other snap action, limit switches is quite broad, and can include industrial machinery, automotive, construction, medical, scientific and aerospace devices, among others. The most common uses are in control systems, as sensory devices in automated machinery, as a safety interface between humans and machines, and as a reliable switch for industrial processes.In terms of the working principle, when the WLG12-P1 is used with a movable actuator, the two armatures, each with two pivots, move the stationary contact to an open or closed position. When the armature is stimulated, usually by an external force such as pressure, temperature, or vibration, the armatures move relative to each other and cause the stationary contact to switch from one state to the other. Since the motion of the armature is linear, the snap action, limit switches are very sensitive to changes in force and are suitable for applications where fast and precise control is needed.All snap action, limit switches require external power for operation. The WLG12-P1 has a nominal voltage of 6 to 24 VAC/VDC, and the maximum voltage is 125 VAC/VDC. The current rating is 0.25A, which is suitable for controlling motors and small electronics. The WLG12-P1 is provided with a detachable digital output and a reliable mechanical indication that allows the switches to be tested and monitored with ease.The contact block for the WLG12-P1 can be chosen from a single-pole, double-pole, and four-pole setup. The contact blocks are made of non-corrosive materials and rated for a long service life. Furthermore, the sealed enclosure offers protection within harsh environments and the contact blocks sub-components are designed to withstand variable temperatures and high vibrations.For applications that require a higher degree of flexibility, the WLG12-P1 comes with adjustable response times. The adjustment is made by an internal contact lever that is designed to either speed up or slow down the motion of the armature to the point where it activates the contact block. This feature allows users to customize its response to various stimuli and allows for faster or slower reaction times as required.In conclusion, the WLG12-P1 snap action, limit switch is a reliable and precise switch for many different applications. Its adjustable response time provides flexibility when controlling motors and other equipment, while its sturdy construction ensures a long service life.
