Snap action switches or limit switches are electromechanical devices used for detecting the position of an object or indicating when a limit has been passed. In a snap action switch, a springloaded actuator is used to physically move contacts within the switch. When a certain threshold force is applied to the contacts they snap into position, activating the switch. It is through this snap action that the snap action switch is known by its name.

These switches are most commonly used in applications where a change in state must be quickly detected. A common example of this is in an amusement park ride where a switch must detect if an object is in a certain position or not. They can also be used for monitoring the speed at which a machine is rotating, as when the speed exceeds a certain limit the contacts will snap open or closed.In terms of working principle, a snap action switch consists of two parts—an actuator and a contact block. The actuator consists of a spring-loaded plunger, which when pressure is applied it pushes the contact block away while the plunger is in motion. When the plunger stops, the contact block is forced back into position against the switch’s contacts, creating a circuit. This causes current to run through the circuit, completing the switch. The spring-loaded plunger then returns to its original position, allowing the switch to be opened or closed again.

The force needed to trigger a snap action switch varies depending on the application, but typically should not be so low that it is easily triggered, or too high that it requires a lot of force to activate. Other aspects to consider when selecting a snap action switch are the temperature and environment in which the switch will be used as well as its mechanical and electrical properties. Snap action switches can be used in a variety of applications, such as industrial process controls, material handling, motors, HVAC systems, and many others.

Overall, snap action switches are an important piece of any electromechanical system and can be used in a variety of applications. With their fast response time and durable construction, they have become an essential part of many industries. They are available in a variety of sizes and designs to meet any application, and can be manufactured to meet specific requirements and specifications.
