Rotary Switches

A rotary switch is an electromechanical switch or control device that has multiple conductive positions. Its name derives from the fact that the switch has a movable contact that is rotated to different positions to make or break a connection. The device usually features a set of multiple contacts connected to a circular rotor and a handle or knob used to select the desired connection or position. Rotary switches are used in a wide variety of applications, from high-voltage and industrial use to radio frequency switching, and are available in many sizes and styles.

71AF30-08-2-03N application field and working principle

The 71AF30-08-2-03N rotary switch is used in a variety of applications, including industrial, communications, and information technology. It is designed to be a universal switch capable of providing reliable switching capability in cameras, robots, power tools, and more. The switch is constructed of high-quality components and is rated for use in both AC and DC applications. It features three sets of two poles and three positions, allowing for two-pole/three-position (TPDT) switching. With its low profile, compact design, and simple operation, the 71AF30-08-2-03N is an ideal choice for applications requiring small size, low cost, and reliable performance.

The 71AF30-08-2-03N works by rotating the rotor, which is connected to the handle or knob. This rotation causes the movable contacts to open or close in succession. As the rotor is rotated, the contacts move from one position to the next, making or breaking the required connection. This allows the application or device to be switched from one circuit or mode to another. The contacts are designed to maintain their contact integrity even after many years of frequent use.

In addition to its TPDT switching capability, the 71AF30-08-2-03N also offers two additional features. It is RoHS compliant, meaning it meets all of the restrictions on the use of hazardous substances in electrical and electronic equipment. And it also has a UL 94V-2 Rating, meaning it is flame resistant and resistant to extreme temperatures. This makes it an ideal choice for applications that require reliable switching through harsh and potentially hazardous conditions.

Conclusion

The 71AF30-08-2-03N rotary switch is a reliable and versatile choice for switching applications of all types. It offers a combination of TPDT switching capability and durable construction in a low-profile, compact design. Its versatile features, such as RoHS compliance and UL 94V-2 rating, make it the ideal choice for applications where reliable switching and high safety standards are required.
