Snap action, limit switches are versatile components which serve two important functions in the automation industry: they protect the motor from overloading and they control the machines motion.

The WLHAL5-LD is a common example of a snap action limit switch. It is a normally open contact limit switch which uses a micro switch and a rigid switching arm as its main components. The device is made up of a plunger and a return spring, and has several other features such as adjustable trip angles, auxiliary contacts, and terminal blocks.

The working principle of the WLHAL5-LD can be broken down into several stages. Firstly, an operating force is applied to the plunger whereby the plunger compresses and actuates the micro switch. Depending on the predetermined trip angle, the micro switch then activates and moves the actuator arm to its opposite position, either opening or closing the contacts.

After the contacts have been actuated, the return spring (attached to the actuator arm) will bring the arm and plunger back to their original position, ready to be actuated again when the next operating force is applied.

The WLHAL5-LD has a wide range of applications across the automation industry, including industrial machines, power tools, home appliances, automotive components, and even medical equipment. Examples of how the device can be used include controlling the movement of axles in a machine or the speed of a combustion engine in an automobile. In addition, it can be used in medical diagnostic devices such as endoscopes and phonocardiographs.

The device is also highly durable and can withstand a wide range of temperatures, making it suitable for a range of applications. Furthermore, it is also resistant to dust and other environmental factors, and can be integrated into most systems with ease.

In conclusion, the WLHAL5-LD is a reliable, easy to use limit switch which has a wide range of applications across the automation industry. With its adjustable trip angles, auxiliary contacts, terminal blocks and resistance to temperature, dust and other environmental factors, it is a versatile and robust device which can be easily integrated into any system.
