The contact plate with the played label shown in the figure is composed of two metal strips approximately one-sixteenth of an inch apart. The first player can reduce the distance between the metal strips by turning on the associated LED indicator by manually turning off the tone generator. The second contact plate, the label in the figure is cleared, and its function is to clear the circuit and extinguish the LED when the distance between the metal strips is manually reduced.
