WLNJ-N

Snap Action, Limit Switches provide efficient, robust, safe and reliable performance in a wide range of electrical switching applications. The WLNJ-N series of snap action limit switch is designed for use in general industrial controlling and automation applications. This series offers a wide range of actuators, various contact forms and operating force levels, as well as a choice of normally open or normally closed contacts. It can be mounted from the front or side of the switch housing and is available in different standard or customized designs.

Application field of WLNJ-N: Snap action limit switches are used in many industrial and consumer applications including water protection, fire protection, instrumentation, counterweight systems, elevators, conveyors, automotive systems, power tools and electrical components. They are also used in robotics and automation systems, where switching accuracy, reliability and repeatability are important factors. The WLNJ-N series has also been developed to meet the stringent requirements of both dry and wet environments, providing a rugged, cost effective solution for even the most difficult switching applications.

Working Principle of WLNJ-N: The WLNJ-N series of snap action limit switches utilizes the principle of a lever arm and fulcrum assembly to actuate the switch contacts. The contacts are located in the upper positions of the switch, and when the lever is moved by an external actuating force, it moves the contact from the normally open to the normally closed position and vice versa. The actuator is connected to a sliding cam and the switch contacts, which open and close the circuit in response to the external force. The switch is designed so that the actuator force applied to the lever must exceed the switch\'s contact-opening threshold before the contacts are opened and reset. When the external force is removed, the contacts snap back to their original positions, thus providing a reliable and secure switching action.

WLNJ-N series of snap action limit switches are designed to provide reliable switching performance in all types of industrial environments and are resistant to shock and vibration. With their optimized mechanical design and high-speed operation, the switches provide excellent repeatability and contact stability. Additionally, WLNJ-N series limit switches are easy to install and operate with their low-profile design and simple wiring. As a result, these switches offer reliable performance and energy savings in a variety of applications.

The WLNJ-N series of snap action limit switches is an excellent choice for any application requiring reliable, repeatable and accurate switch action. Whether the application is in industrial control, robotics, automation, instrumentation or other applications, these switches offer a cost-effective, easy to maintain solution that meets today’s tough requirements.
