SW5 (toggle or momentary) is the switch that turns the VCO on or off. R8 is a one megohm linear potentiometer (in series with 27k fixed resistor R7) which sets the actual frequency of the VCO (within the range selected by SW6). SW7 is a six position rotary switch which selects which of six capacitors also sets the VCO frequency range.
Motorized potentiometers can be slide or rotary potentiometers. There also exist multiple turn motorized potentiometers. [4] The end of travel may be detected using limit switches, a peak in motor current as the mechanism stalls, or a separate resistive element used for position feedback.
The mechanical type is commonly employed as a manually operated "digital potentiometer" control on electronic equipment. For example, modern home and car stereos typically use mechanical rotary encoders as volume controls. Encoders with mechanical sensors require switch debouncing and consequently are limited in the rotational speeds they can ...
Common control components used include potentiometers, variable capacitors, and rotary switches. An example where the knob does not produce a variation in an electrical signal may be found in many toasters , where the darkness knob moves the thermostat in such a way as to change the temperature at which it opens and releases the cooked toast.
The skeleton potentiometer works like a regular circular potentiometer, but is stripped of its enclosure, shaft, and fixings. The full movement of a skeleton potentiometer is less than a single turn. The other type is the multi-turn potentiometer which moves the slider along the resistive track via a gearing arrangement. The gearing is such ...
