Snap action, limit switches are commonly used to provide sensing capabilities in a variety of applications, from medical devices to industrial automation systems. The WLCA2-2LE is a snap action/limit switch designed for specific use in demanding applications.

The general design of the WLCA2-2LE consists of a base with two terminals, a plunger and actuator arm, and a contact set. The base can be installed on any flat surface using screws or rivets. The two terminals provide the connection between the switch and the rest of the system. The plunger and actuator arm attaches to the one of the terminals and is moved by a force such as a lever or pushed button to actuate the switch. The contact set includes contacts made of conductive material and a plastic actuator. The actuator moves when the plunger and actuator arm is moved by the external force and then contacts the other terminal, thus completing the circuit.

Thus, the working principle of the WLCA2-2LE is simple. When the external force acts on the plunger and actuator arm, it is pushed forward. This causes the actuator to push against the contacts and bridge the contacts to the other terminal, thus closing the circuit. When the force is removed, the plunger and actuator arm returns to its original position due to its spring-loaded design and the actuator is pushed away from the contacts, thus breaking the circuit. This can be used to open and close the circuit in response to the external force.

The WLCA2-2LE is particularly suitable for use in demanding applications because of its combination of features. It is designed with a durable stainless steel contact that stands up to corrosive and wet environments. The switch also has a protected operating temperature range of -55°C to +85°C and a high shock and vibration resistance. It is also UL and CSA certified, providing added safety and reliability.

The WLCA2-2LE can be used in a variety of applications such as medical devices, industrial automation systems, home security systems and automotive systems. In medical devices, the switch can be used to control the flow of fluids, turn equipment on and off, and monitor pressure. In industrial automation systems, it can be used to detect the presence of objects, monitor temperature, control machinery, and monitor pressure. In home security systems, it can be used to detect and control doors and windows, and to monitor the presence of trespassers. In automotive systems, it can be used to detect and control the door locks and windows, to monitor the engine temperature, and to monitor the seat belt status.

In conclusion, the WLCA2-2LE is a snap action/limit switch designed for specific use in demanding applications. It features a durable stainless steel contact and is UL and CSA certified, providing added safety and reliability. The working principle of the switch is simple and can be used in a variety of applications such as medical devices, industrial automation systems, home security systems and automotive systems.
