Snap action, Limit Switches are devices used for disconnecting and establishing electrical circuits by switching off and on of currents. They are in use in a wide range of applications, such as industrial machines and equipment, process control systems, robots, automotive applications and more. As the name suggests, they switch off and on electromechanically due to forces generated externally like pressure, inertia, heat, torque, vibration or any other physical force. WL01HAL4-LD snap action, limit switches are no exception.

The WL01HAL4-LD snap action, limit switches are based on a micro switch mounted on a rectangular casing. The switch features a single-pole, double-throw (SPDT) switch, with a set of three terminals. These terminals are connected to a pre-fixed activation force and a re-energizable mechanical element. This makes it ideal for applications in which the switch must be actuated repeatedly. This type of switch is also very reliable and can be used for switching off and on of currents through a full range of voltage and current ratings.

WL01HAL4-LD snap action, limit switches are typically used for applications in which switching off and on of currents must be performed at a predetermined force. Examples of this type of application would include level control, sensing of position, flow rate monitoring and temperature control. In addition to these applications it can be used in a range of other industrial and process control applications.

The WL01HAL4-LD snap action, limit switch works on the principle of mechanical actuation. When the preset activation force is applied, the electrical contacts of the switch open and close alternatively. This opens and closes the electrical circuit, thus switching off and on the current. The re-energizable mechanical elements in the switch ensure that it is able to open and close the contacts even with repetitive switching operations.

In conclusion, the WL01HAL4-LD snap action, limit switches are suitable for use in a wide range of industrial and process control applications. They are reliable and can operate with a full range of voltage and current ratings. The re-energizable mechanical elements make it ideal for applications in which the switch must be actuated repeatedly.
