Electronic components are basic electronic element or electronic parts usually packaged in a discrete form with two or more connecting leads or metallic pads. Electronic Components are intended to be connected together, usually by soldering to a printed circuit board (PCB), to create an electronic circuit with a particular function.

Is there a rotary device that can be used to control an input interface that has +/- switches on a board?
For example, an FM tuner board that has + and - (momentary) switches for tuning. Instead of using push button switches, I would like to use a rotary device like a tuning knob to control the frequency selection for this board. Ideally, this would be a device with three terminals: +, - and GND. When the knob is turned clockwise, it should momentarily short + and GND, once per some degree of rotation, say 30 degrees. When the knob is turned counterclockwise, it should momentarily short - and GND, once per the same degree of rotation.
Is there a device like this, or do I need to build one using a rotary encoder and some logic?
