Snap action, limit switches, such as the WLS1A11BQ-P02 model, have many useful applications in various mechanical, electrical and automotive systems. This article will discuss the most common uses of such switches and how they work.

In terms of application, snap action limit switches, such as the WLS1A11BQ-P02, are typically used to detect the presence of an object or to open or close an electrical circuit. The most common applications include door position detection, automation systems and limit detector. In door position sensing, for example, the switch is used to detect whether the door is opened or closed. In automation systems, such switches are used to switch on and off the action of the system. Finally, in limit detectors, the switch is used to detect when a certain position is reached by a movable object.

The workings of these types of switches are based on a mechanical lever/spring combination. The lever and spring are connected to an electrical contact. When an external force is applied to the lever, it causes the switch to be actuated. The switch is normally in the “OFF” position, and when the actuation force is applied, the switch “snaps” into the “ON” position. This action creates an electric connection between two terminals and creates a circuit, allowing current to pass through it and activate the desired action. Once the force is released, the switch will again move back to its “OFF” position, breaking the electric connection and stopping current from passing.

Depending on the type of switch and the application, certain adjustments can be made. Some models have adjustable mechanical settings that affect the force that must be applied to actuate the switch. In addition, different electrical settings, such as current or voltage ratings, can also be adjusted.

In summary, snap action limit switches, such as the WLS1A11BQ-P02 model, are commonly used to detect and switch electric circuits on and off. The mechanism for this action is based on a lever/spring combination, with the actuation force causing the switch to “snap” from the “OFF” position to the “ON” position. In many cases, these switches can be adjusted according to application requirements. Each system should be carefully analyzed and the appropriate type of switch should be chosen for the best possible performance.
