Snap Action, Limit Switches

Snap action and limit switches are simple mechanical switches capable of opening and closing a circuit, typically at a fixed position in a switch’s movable component. They are widely used in a variety of applications, such as in industrial, medical, and domestic areas.

What are Snap Action & Limit Switches?

Snap action and limit switches are electromechanical switches that are designed to perform a specific function, either opening or closing an electrical circuit. They consist of a switch body, which houses the movable component, and other parts that work together to open or close the circuit. A spring, usually a metal leaf or coil, applies pressure to the movable component, pushing or pulling it into position. The position at which the circuit opens or closes is referred to as the switch’s “set point.”When the set point is reached, the switch will “snap” into the appropriate position, either making or breaking the circuit. This “snap” action, as the name implies, is instantaneous and produces an audible click, allowing the user to quickly detect the switch’s position.

Types of Snap Action & Limit Switches

Snap action and limit switches are available in a variety of styles and configurations, designed to meet the specific needs of a variety of applications. Common types include toggle, push-button, rotary, miniaturized, and special purpose limit switches. The type of switch used should be based on the expected application and individual requirements.

Application Fields & Working Principle

The application fields of snap action and limit switches are extensive and depend largely on the decision of the user. Many applications utilize the “snap” aspect of the switch to detect when a limit or setting has been reached. Industrial applications such as conveyor systems and large machines utilize limit switches to prevent them from running too far or to detect when a part is in the correct position.In medical and domestic settings, snap-action switches are often used to detect when a door is opened or closed, or when a light switch is turned on or off. In these cases, the switch is used to detect the position of the opening or closing object and interrupt the circuit accordingly.When a snap action or limit switch is activated, its movable component is will be pushed or pulled into the specified position. As the set point is reached, the spring will be compressed and the switch will move into its intended position. This movement will allow the circuit to be opened or closed, depending on the switch’s design.

Advantages & Disadvantages

The primary advantage of snap action and limit switches is their unparalleled reliability and durability. The simple mechanical design ensures that these switches are capable of withstanding the environmental conditions of a variety of applications, from industrial to home. Additionally, their robust construction ensures that these switches can be operated for long periods of time without performance degradation.However, these switches do have their drawbacks. snap action switches are not suitable for applications requiring precise switching, as their bulky construction prevents them from being able to detect minor variations in position. Additionally, the audible “click” produced by the switching mechanism may not be suitable for certain applications, such as consumer electronics.

Conclusion

Snap action and limit switches are simple but reliable electromechanical devices that are capable of opening and closing a circuit in a variety of applications. They rely on the action of a spring to push or pull a movable component into position. These switches offer a variety of advantages, such as robust construction and reliability, but may not be suitable for all applications due to their bulky construction and audible click upon activation. To determine the best solution for a given application, it is important to consider the individual requirements and available options.
