Snap Action, Limit Switches – Application Field and Working Principle

Limit switches are useful devices that act as position-sensing elements for automation and control applications. They become activated, or "trip," when a predetermined limit has been reached, thus providing a reliable, cost-effective solution for automated control and machine monitoring.One type of limit switch is the snap-action switch, which offers extreme precision and repeatability. Snap-action switches respond quickly and accurately to a predetermined limit, making them suitable for applications involving rapid motion. They are typically used in combination with mechanical components such as levers, buttons and levers, cylinders, latches, and other mechanisms.The snap-action limit switch works through a mechanical-electrical linkage that allows for reliable and consistent operation in a wide range of applications. The switch’s housing is made of insulating plastic, and contains a spring-loaded internal contact and a plunger. The plunger is actuated by external mechanical force, such as a lever or button. When the plunger is actuated, it trips the internal contact, allowing electrical current to flow from the source to the load.Snap action limit switches are usually classified according to their motion pattern. Momentary switches are self-resetting, which means that they automatically reset after they trip. These switches are typically used in applications requiring on/off sequences, such as doorbell circuits. Latch-on switches stay in the closed position after they have been activated, and must be manually reset.In terms of their physical construction, snap-action switches are typically composed of an actuator, a housing, and electrical contacts. The actuator is typically composed of a lever or plunger, which is actuated when external mechanical force is applied to it. The housing is usually made of insulating material, and it contains the internal contact and the actuator. The electrical contacts are either normally open (NO) or normally closed (NC), depending on the application requirements.In terms of their application field, snap-action limit switches can be used in a wide range of installations, from domestic and industrial applications to laboratories, research centers, and military applications. For example, they can be used to detect the presence of an object in a machine, or to measure levels or distances. They can also be used for monitoring and control purposes, such as for controlling the speed or direction of a motor, or for determining the position of the components in an automated system.In conclusion, snap-action limit switches are versatile and reliable devices that are used in a wide range of applications. They are easy to install and can be adapted to meet almost any positioning requirement. Their accurate and reliable performance makes them suitable for use in a variety of environments, from domestic and industrial installations to research and military applications.
