Snap action switches, also referred to as limit switches, are electromechanical devices used to sense and control electrical circuits. WLD28 snap action switches are a type of limit switch typically used in industrial automation and control applications, such as motor starters, conveyors, elevators, and robotics. WLD28 switches are designed to detect an object, and still operate reliably, even after being immersed in liquids. In addition, WLD28 switches are capable of handling both low and high-pressure applications. By using a rugged construction and sealed enclosure, these devices can reliably record and monitor the position of objects in extreme environments.

The construction of WLD28 switches includes a switch blade mounted on a rod and an actuator plunger. The switch blade is made from a conductive material and is curved to fit snugly against the plunger when not in use. The plunger is connected to a trigger mechanism, which is activated when an object is detected. This trigger mechanism is tightly sealed to prevent any leakages, which ensures reliable and accurate operation in even the most extreme conditions.

The WLD28 switch is designed to operate under two types of Circuit-on-Reset (COR) applications: a close contact, or a non-contact. Under a close contact application, the plunger is moved along the switch blade, resulting in a brief period of electrical contact being made between the two components. This results in a pulse of electrical current being transmitted to the device. If a non-contact application is required, the plunger is moved a predetermined distance and the electrical current is sent through a non-metallic connection.

The WLD28 switch is typically wired to an input or output device, or an electronic controller. When an object is detected, the plunger will move and trigger the switch, resulting in an electrical signal being sent. This signal can then be used to activate any type of function, such as an alarm, a motor, or a display. The amount of time that the switch remains closed or open depends on the type of device being controlled and the type of application being used.

The WLD28 switch is a reliable, efficient, and cost-effective solution for sensing and controlling objects in industrial automation and control applications. It is ideal for applications that require accurate and reliable response times, even in the most extreme conditions. With its rugged construction and reliable operation, the WLD28 switch is the perfect solution for any industrial setting.
