Snap action limit switches have become an extremely common apparatus in industrial and robotics technology.

Whether it\'s used as a safety measure or a way to actuate a specific action, it\'s important to understand the 83153713 applications field and working principle of a snap action limit switch.

A snap action switch is a general purpose contact mechanism used to operates in two positions effectively. The switch uses a mechanical energy source, such as a spring, to close a switch contact when the activating force reaches a certain threshold, which is known as the “snap-action” movement.

The most common type of contact used in snap action limit switches is SPST (single pole, single throw); however, SPDT (single pole, double throw) and DPDT (double pole, double throw) contacts are also available for applications where increased switching power is needed.

The most common application for a snap action limit switch is actuating a safety measure, for example, in the industrial and robotics technology applications. The switch, when actuated, stops the motion of the device or robot, which in turn reduces the chance of injury.

Snap-action switches are also used to control or indicate the presence of various processes in automation systems. Examples of these applications include controlling the flow of liquids and gases, detecting the position of a machine, and controlling the speed of a motor.

The operating principle of a snap action limit switch is based on the application of force or pressure to a button that closes its contact points. The force required to actuate the switch is determined by the spring tension and its placement relative to the contacts. As the amount of force applied increases, the contacts of the switch close at a predetermined sensitivity level. Once the contact points are closed, the switch will remain in the closed position.

The sensitivity of the snap action switch can be adjusted through the use of shims or by adjusting the tension of the actuator spring. In addition, the contact points of the switch can be designed to operate at a specific voltage, current, and resistance, depending on the application.

In order to prevent accidental actuation, the snap action limit switch is often designed with a “snap-lock” feature, in which the actuating force for the switch must be applied for a predetermined amount of time. This time can be adjusted depending on the application.

In summary, snap action limit switches are very useful in many industrial, robotics, and other automation applications. They are simple, reliable, and inexpensive components. By understanding the 83153713 application field and working principle of a snap action limit switch, engineers can easily apply it to their designs.
