The WLG12-LD is an impeller style limit switch designed for applications where a low profile and space or weight savings are required. The unit is designed to provide an equivalent action to conventional rotary and plunger type switches and is therefore ideal for situations where this type of action is needed but space restrictions are an issue. The WLG12-LD is part of the snap action switches and limit switches range, being a snap action switch it features a snap action contact system that can be operated by a lever, plunger, roller or cam.

Application field

The WLG12-LD has a range of applications from industrial automation and machine control to the more specialist electron microscopy and medical equipment. Its compact design and lightweight construction make it suitable for use in a variety of environments that require a low profile, limited space and a low weight solution.

Working principle

The switch is actuated by a lever, plunger, roller or cam when the limits of the operating range are reached. The operating force or normal load is transferred between a roller and a cam on the switch and a plunger or roller arm mounted on the target system. The contact system is set to the predetermined position, the roller contact is pressed onto the cam and the contact spring is subsequently forced open. This action causes an audible click from the switch indicating the switch has been actuated.

The WLG12-LD also uses a highly efficient non-contact magnetic latching system. This patented system not only reduces the need for power, but also delivers an extended operational life. By utilizing a magnetically driven solenoid, the switch can be switched in and out of the latching mode at high speed with a very low current consumption.

With its compact movement and small footprint, the WLG12-LD provides an extremely reliable solution for low profile and weight savings without sacrificing reliability or performance. The switch features a range of operating temperature ranges and various contact configurations, making it a suitable solution for a wide variety of applications where an effective switch on a limited space is needed.

Conclusion

In conclusion, the WLG12-LD is an ideal solution for a range of low profile, limited space and weight saving applications. It is part of the snap action switches and limit switches range and features a non-contact magnetic latching system that extends the operating life and reduces power consumption. Its small footprint and range of operating temperature ranges make it suitable for a wide variety of applications where an effective switch is needed on a limited space.
