Реферат: Numerous devices and systems include rotary switches or other rotary encoders. A rotary encoder typically translates an object’s rotational position into an encoded data value. For example, a rotary encoder can include a knob that can be rotated by a user, and the current rotational position of the knob can be converted into a digital value. Different rotational positions of the knob typically correspond to different digital values, and the digital values generated by the rotary encoder can be used to perform various functions. As specific examples, rotary encoders can be used as volume controls or tuning dials for radios or as intensity controls for light sources. Unfortunately, rotary encoders typically have a finite number of positions for which different digital values can be generated. The diameter of a rotary encoder can increase significantly as the number of finite positions increases. This can increase the size, weight, or cost of the rotary encoder or of an overall system that includes the rotary encoder. The current disclosure involves an apparatus for rotary encoding includes a knob configured to be rotated. The apparatus also includes multiple switches each configured to selectively form or not form a connection based on a current rotational position of the knob. The apparatus further includes a controller configured to generate or use a digital value associated with the current rotational position of the knob. The digital value is defined by which switches have or have not formed connections. Locations where the switches form the connections are selected such that the digital values uniquely identify different rotational positions of the knob and are non-sequential as the knob is rotated.
