Snap Action, Limit Switches

Snap action, limit switches are devices that contain two pieces of metal that are held together by tension and connected to a contact point. When force or voltage is applied to this contact point, the two pieces of metal will move apart, causing the contact point to break. This action is referred to as a “snap action” and is usually used to turn electrical signals on and off.

83732327 Application Field and Working Principle

Snap action, limit switches are often used in industrial automation systems, such as packaging machines and conveyor systems. These switches are designed to provide a reliable, repeatable, and accurate switching action for various actions or processes in industrial applications. They are typically built with two pieces of metal, a base, and a movable contact. The base mounts onto the system, while the movable contact, when force is applied, will snap open and close the circuit.

When force is applied to the contact point, it will cause the arms of the snap action switch to open. This opens the circuit and is referred to as the “snap action”. Depending upon the type, the switch can be pre-programmed to open or close either at a specific voltage or pressure.

The snap action switch is usually composed of two contact pieces, a base and a movable contact. The base is typically fixed to the system while the movable contact is mounted onto the base with a tensioned spring. As an external force is applied to the switch, the arms of the switch contact pieces will open, allowing the circuit to be opened or closed.

Snap action, limit switches are often used in industrial applications due to their reliability, repeatability and accuracy. They can provide an accurate control over processes and can be utilized in many industrial automation systems. In addition, the snap action switch is cost-effective and requires minimal maintenance, making it a desirable choice for many applications.

Switches of this type come in a variety of sizes, shapes, and styles. The most common configuration is a single pole, double throw (SPDT) switch. This switch will open and close a single circuit depending upon the amount of force on the contact. The SPDT switches are used for control, monitoring, and switching applications. In addition, there are switches available in the form of cylinders and levers, as well as a variety of diaphragm switches.

Snap action, limit switches are designed for a variety of applications and are heavily used in industrial automation systems. They are reliable, accurate, cost-effective, and require minimal maintenance. They offer a reliable and repeatable method of controlling processes and circuits while being available in a variety of sizes, shapes, and styles.
