    en.wikipedia.org/wiki/Indicator_(distance...

    The classic mechanical version, called a dial indicator, provides a dial display similar to a clock face with clock hands; the hands point to graduations in circular scales on the dial which represent the distance of the probe tip from a zero setting.

  3. Rotary dial - Wikipedia

    en.wikipedia.org/wiki/Rotary_dial

    On the rotary dial, the digits are arranged in a circular layout, with one finger hole in the finger wheel for each digit. For dialing a digit, the wheel is rotated against spring tension with one finger positioned in the corresponding hole, pulling the wheel with the finger to a stop position given by a mechanical barrier, the finger stop.

    A coil, with another coil or magnet inside, used in flippers, kickers, and other mechanical devices. When the coils are energized, the opposing magnetic fields cause the inner piece to move. Solenoids are the principal method that pinball machines use to create movement in mechanical objects on the playfield. [53]

  6. Dialling (telephony) - Wikipedia

    en.wikipedia.org/wiki/Dialling_(telephony)

    Initial pushbutton designs employed mechanical switches, so that each button activated certain combinations of capacitors and inductors of an oscillator, while later versions used semiconductor logic chips to synthesize the frequencies. The tones are decoded by the receiver to determine the keys pressed by the user.
