Snap Action, Limit Switches

Snap action, limit switches are mechanical switches that provide an instant response when their operation is triggered. They are often used as safety circuits in industrial machines and automation systems. The WLG2-LD-DTGJ03 is one such switch, and it is ideal for a wide range of applications.

Applications

The WLG2-LD-DTGJ03 offers a robust and reliable solution for applications where it is important for the switch to have a fast response and prevent any risk of machine failure. It is especially useful in situations where the switch must operate continuously and reliably. Examples include, but are not limited to, applications where safety is of paramount importance such as those found in electrical circuits that are used to operate pumps or electric motors.

The WLG2-LD-DTGJ03 has a long product life and is suitable for harsh environments such as submerged or immersed installations. This switch has also been designed for use in watertight enclosures. It is also suitable for use in extreme temperatures and can operate in temperatures ranging from -22°F to +248°F (-30°C to +120°C).

Working Principle

The WLG2-LD-DTGJ03 features a snap-action mechanism which consists of a bi-metal disc, a control lever which pivots around an anchor point and a magnetic armature. The switch works by drawing a magnetic field to the armature when the ambient temperature changes. This causes the bi-metal disc to bend and the control lever to pivot around the anchor point quickly, creating a burst of high contact pressure.

When the magnetic field is removed, the contact pressure drops off and the control lever returns to its original position. The switch has been specifically designed so that the magnetic field only affects the armature when the contact pressure drops to a predetermined level, effectively resetting the switch. This operating principle of the switch ensures that the contact pressure is consistently high, providing reliable operation even after prolonged use.

The WLG2-LD-DTGJ03 is also designed with a momentary contact structure which provides a “make and break” type of operation, allowing for an instant response time. This feature is especially useful in applications where it is important for a switch to respond as quickly as possible to changes in the environment.

Conclusion

The WLG2-LD-DTGJ03 is a reliable, robust and highly adaptable switch that offers a versatile solution for a variety of uses. Its snap action principle ensures a fast and reliable response time and its momentary contact structure allows for an instant response when needed. This makes it the ideal switch for any application where safety is a priority and where consistent, reliable performance is required.
