Snap Action, Limit Switches

Snap action limit switches, like the 831708C1.BL are an important part of industrial automation and are used to control and monitor the running of automated machinery. They are typically used to measure the presence of an object and in some applications, such as to detect a change in direction. They can also be used in safety circuits, and to measure levels in a process.

The working principle of a snap action limit switch is simple and reliable. Inside the switch is a spring-loaded switch arm which is attached to a contact. When the arm is moved, either by mechanical, electrical or magnetic input, the contact opens or closes. This activation triggers a signal, which can then be used by the controlling system to carry out the appropriate action.

Snap action limit switches are available in a variety of sizes, ranges and configurations. Most models are available in single pole and double pole designs, with a wide variety of actuation force options. Often, limit switches have adjustable settings or multiple building switches to adapt to the varying needs of different applications. The 831708C1.BL is fitted with a built-in LED which makes it easier to diagnose exactly when the contact has been made.

Snap action switches are rugged and reliable, capable of performing from -40° to +70° Celsius, even in moist and dusty environments. This makes them ideally suited for applications that demand the highest quality of Industrial Automation such as heavy machinery, process control, etc.

The 831708C1.BL snap action limit switch is suitable for both indoor and outdoor applications and is designed to be highly weatherproof as it is provided with a fully sealed enclosure. It also features greater durability and longer operating life, as the contact arm is less likely to move after it is activated. This makes it ideal for applications such as conveyor systems, where it is often necessary to detect when an item has finished travelling along the conveyor.

Snap action limit switches used in industrial automation offer a range of features that make them well-suited for a variety of applications. They are typically used to measure the presence of an object and in some applications, such as to detect a change in direction or measure levels in a process. With their simple, reliable working principle and wide range of models, limit switches offer an effective solution for many industrial automation applications.
