Snap action switch limit switches are electromechanical actuators used in the automation industry to detect the opening and closing of a machine, allowing for the functioning of the machine to be automated, making machine operation safe and efficient. The WLCA2-8TS-N model of snap action, limit switches is one of the most popular models on the market, as it is a feature-rich device that has all of the necessary components to make it an ideal switch. This article will explore the WLCA2-8TS-N’s application field and working principle.

Application Field

The WLCA2-8TS-N limit switch is designed to be used in mechanical, such as conveyors, elevators, and material transportation systems, as well as electrical, applications, such as circuit protection, machine monitoring, and temperature control. The primary application is to provide a physical means to detect the opening and closing of a mechanical system for automated operation, allowing for safe and efficient operation. This switch can also function as an emergency stop switch, allowing for the operator to cease operations and maintain system safety.

Working Principle

The WLCA2-8TS-N limit switch is a snap action, meaning that it is designed to open and close the switch with a snap. This is accomplished using two contacts and a spring-loaded lever system. When the actuator is engaged, the spring-loaded lever opens the contacts and creates an open circuit. When the actuator is disengaged, the lever closes the contacts and creates a closed circuit. This closed circuit can then be used to signal to other actuators or automation systems, allowing for functions or safety protocols to be triggered.

The contacts of the switch are made of a durable material, such as stainless steel, and can be used with different voltage and current levels. They also offer a high number of cycles and have a long life expectancy, making them ideal for use in automation systems. The switch is protected via the use of rubber gaskets and other protective mechanisms, which helps to prevent dirt and moisture from entering the switch.

Additional Features

The WLCA2-8TS-N switch is also equipped with additional features for increased safety and efficiency. The contacts of the switch are configured to be “positively-opening”, meaning that the contacts will open when the actuator is engaged, regardless of any force applied to them. There is also an internal locking mechanism that prevents the contact from closing while the actuator is engaged. This prevents the switch from accidently closing and potentially causing an accident.

The switch is also equipped with LED indicators that can be used to easily monitor the status of the switch. The LED\'s can be green for when the contacts are closed and red for when the contacts are open, allowing for quick visual identification of the status of the switch without needing to open it.

Overall

The WLCA2-8TS-N snap action limit switch is an efficient, robust, and widely used form of limit switch. Its features, such as its positively-opening contacts, rubber gaskets, internal locking mechanism, and LED indicators make it a go-to switch for many industrial automation applications. With its numerous features and capabilities, it is easy to see why the WLCA2-8TS-N is a popular choice when choosing a limit switch.
