Rotary Switches

A rotary switch is an electrical switch that works by rotating a concentric dial and selecting an output position from the range of possible positions provided by the construction materials. They are typically used for basic selections and are available in a variety of sizes and shapes. The most common type of rotary switch is the 71C302111N-1102N, which is a double pole and multi-position switch.

Working Principle of 71C302111N-1102N

The 71C302111N-1102N rotary switch is a double pole and multi-position switch, which means it has two sets of contact points, each having four position settings. The switch works by rotating the dial and selecting an output position from the range of possible positions provided. As the dial is rotated, the mechanical linkages on the inside of the switch activate and deactivate contact points, allowing the user to select one of the four distinct functions. The current flows through the selected setting and is then sent to its destination.

As the switch is activated and rotated, the contact points are first pushed together then switched off. This ensures a short contact time, reducing wear and tear on the contact points, resulting in a longer life-span.

The switch is usually made of either plastic or metal. For applications which are likely to experience a lot of vibration or shock, it is recommended to use a metal casing. Plastic casings may be prone to cracking or breaking under extreme conditions.

Conclusion

The 71C302111N-1102N rotary switch is a 4-position, double pole, multi-position switch. It is used in many different fields and applications, such as industrial and electrical applications, communication and HVAC equipment, lighting, measurement and calibration, and clockwork mechanisms. The switch works by rotating the dial and selecting an output position from the range of possible positions provided. The switch is usually composed of either plastic or metal.
