Rotary Switches

A rotary switch is a kind of switch that is operated by turning a cylindrical control element, a "rotary knob", gear selector, or a generator rotor. When the knob is turned, a cam moves a spring-loaded contact ad through a series of pointed contacts, making or breaking the electrical connection as it goes. Therefore, several switches can be placed in one housing, and they can remain mechanically structured while not having to move linearly. With their long, thin shape and multiple contacts, rotary switches are perfect for applications that require control of many circuits packed in a limited space.

One of the popular models, 71BF30-03-1-10N, is a rotary switch designed to provide 10 circuits within three layers in both switch and jumper configurations. This switch is ideally suited for industrial as well as commercial applications, including telecommunications systems, computer peripherals and software, test instruments, or any other equipment needing a rotary position switch.

Application Field

The 71BF30-03-1-10N rotary switch can be used in telecom, alarm and security, instrumentation control, aerospace, automotive, computer and networking, power supply, gaming and entertainment, audio and video, as well as industrial automation, construction, and sports equipment. It is also suitable for general-purpose switching applications such as light, heat and power circuits, lighting and sound control.

Working Principle

The 71BF30-03-1-10N rotary switch is operated by the turning motion of the rotary knob on its control element. The turning motion can be done in either a clockwise, counterclockwise, or bidirectional manner. As the knob is turned, a cam is activated that moves a spring-loaded contact down through a series of contact points, allowing and breaking the electrical current as it passes them, similar to the design of a drum switch.

When the contact reaches the bottom point, it is pushed back up, resetting the switch to its "off" position. This reset point is usually the top or bottom point of the switch, depending on the switch\'s design. In addition, the knob can be locked in place so that the switch remains in the same position and the contacts remain engaged.

Conclusion

The 71BF30-03-1-10N rotary switch is a great choice for applications that require multiple circuits to be controlled in a limited space. Its long, cylindrical shape and flexible operation makes it an ideal solution for varying needs and industries, such as telecom, instrumentation control, power supply, and entertainment. It is easy to operate and relatively maintenance-free, making it a great choice for commercial and industrial applications.
