Williams, 1992HS2 white green switches will not work. Sometimes i get the outhole switch working, sometimes i get the all of them working. Bit even when i do they will only work about 5 to6 games then won't work again. I must state that there is alkaline damage on the board, just didn't understand why it sometimes will work, and sometimes won't

Communication in digital electronics is the binary world of on (1, or HIGH)) and off (0 or LOW). A voltage that is near 0 is interpreted as a LOW, a voltage above a certain level is a HIGH. Between the extremes is an ambiguous zone where there is no certainty with what the signal will result in. It may bounce arbitrarily between HIGH and LOW. If there is corrosion damage that is causing some resistance in components, this can result in the logic voltages floating in this ambiguous zone.
