Snap Action, Limit Switches are widely used for mechanical and electrical devices for ensuring the accuracy of operator operation. The WLCA2-2NLD-N is one kind of snap action switches with various features. Generally, it is mainly applied in safety protection and signaling to indicate the status of small presses and large machines, such as molding machine, large processing machine, elevator, injection machine and so on.

WLCA2-2NLD-N application fields include special perform machine, medical device and communication industry as well. It made of high quality material and is safe to use with strict production standard. Whenever people want to get automatic protection and control service, WLCA2-2NLD-N is the best choice.

The construction of a WLCA2-2NLD-N switch incorprates a movable contact part, a stationary contact part and switch actuator. The special designed contact part can run stably in order to ensure the contact surface does not have any damages. It is mainly used to control the movement of an operator into two directions and also for automatic micy adjustment in day-to-day movement.

In addition, the switch can operate with various current Input signals. It can detect  limit of motion towards two directions, and is able to sense the position of moving parts close to its operating point. When the moving part crosses its pre-set distance, the switch actuates immediately in its  “forward” or“reverse” mode. This helps to protect the motor. Moreover, the switch can control the start and stop functions of machines use since it uses the direct signals for switching the machine’s power supply.

The working principle of the WLCA2-2NLD-N can be briefly explained as follows. Its limit of rotation is set by the contact surface between the movable disc and stationary disc. When the switch senses the limit of motion and reaches its operating point, the contact surface between the movable and stationary disc will changes, allowing the movable disc to connect with the stationary disc which makes the switch actuate.

In conclusion, WLCA2-2NLD-N is solid, protected and designed for protect motor with high accuracy and sensitivity. Therefore, it is widely used in safety protection and signaling in various industries. It is regarded as the most efficient and reliable limit switch.
