In VIKIWAT, you will find rotary switches, which switch different (more than two) positions by rotation. They are used for switching fan's speed, radio's frequencies, the programs of household electrical appliances and many others. Often, the rotary switches have more than one section, which increases with times, the possible rotations. The rotary switches for PCB are often sealed and can be secured by threads and nuts. The electric connection is achieved by soldering of the pins(legs).
