First, the left, right, and up and down are divided into groups, and the wiring is performed by grouping the lines. This requires personnel experiments to understand the mystery in it. The wiring of the rotary switch is more complicated, but the internal combination structure is relatively simple.
It is mostly composed of an operating mechanism, an electric shock, a shaft, a handle, a pointing device, and a contact system, thereby facilitating a loop control circuit. The universal changeover switch is small in size and does not take up much space, and is generally concealed.
However, it has more functions, can achieve universal conversion, better insulation performance, flexible conversion operation, compact structure, safe and reliable performance.

The throw defines how many positions the switches poles can be connected to. This switch type typically has two terminals and is referred to as a single-pole switch. SPDT rotary switches make or break the connection of a single conductor with either of two other single conductors. These switches usually have three terminals and are commonly used in pairs.
SPDT switches are sometimes called three-way switches. DPST rotary switches make or break the connection of two circuit conductors in a single branch circuit.
They usually have four terminals. DPDT rotary switches make or break the connection of two conductors to two separate circuits. They usually have six terminals are available in both momentary and maintained contact versions. Function: Unlike push button switches available in momentary or latching function to operate a device or function. This means that when moved into position the rotary switches will stay in place and will require to be moved again to perform the next function.
How are they able to avoid the size and cost trade-off? This article will explore answers to many more interesting questions. The image above shows a conventional rotary switch made up of wooden ply and metal. The top of the switch has a knob which works as an actuator and is rotated to put the switch into different working states. Also seen in the image above is a metallic ball which is held by two thin rectangular plates placed on the lower side of knob.
The projections at the bottom are the metal contacts through which the switch is electrically connected to the circuit. Wires are generally soldered on these contacts. The knob extends till the bottom and is strongly punched at the end so that the different components can be held at their respective positions. Technically, the wooden plies shown in the image above are called decks or sections. The metal plate which forms the bearing also has extensions which hold the knob and the wooden ply together.
The structure of the knob can be understood more thoroughly when it is removed from the wooden ply assembly.
