Two control knobs for a heating/cooling system. The left knob controls the temperature while the right controls the fan speed. A control knob is a rotary device used to provide manual input adjustments to a mechanical/electrical system when grasped and turned by a human operator, so that differing extent of knob rotation corresponds to different desired input.
Thus a rotary switch provides greater pole and throw capabilities than simpler switches do. Rotary switches were used as channel selectors on television receivers until the early 1970s, as range selectors on electrical metering equipment, as band selectors on multi-band radios, etc. Modern rotary switches use a "star wheel" mechanism to provide ...
This makes them especially suitable for encoding devices such as a remote controller. Rotary DIP switches contain multiple electrical contacts, one of which is selected by rotating the switch to align it with a number printed on the package. Some have a knob that can be turned by fingers, or a small slot that requires a screwdriver to
In industry, rotary switches are used for control of measuring instruments, switchgear, or in control circuits. For example, a radio controlled overhead crane may have a large multi-circuit rotary switch to transfer hard-wired control signals from the local manual controls in the cab to the outputs of the remote control receiver.

The rotary machine switching system, or most commonly known as the rotary system, was a type of automatic telephone exchange manufactured and used primarily in Europe from the 1910s. The system was developed and tested by AT&T's American engineering division, Western Electric , in the United States, at the same time when Western Electric was ...
Thus the term cam switch has been used for such and similar devices over the years. Schuckert also supplied the "carbon control switch" designed by Natalis since 1901 with copper-carbon switching devices with spark-blowers (common spark blowers for direct current or single-spark blowers for direct and alternating current).
