Monday Night Football and earlier: the doubled flipper EOS switch

The flipper end-of-stroke assembly is two switches. The one on the left, fitted with a diode, is a normally open matrix switch that closes when the flipper is up and drives lane change and high score initials. The right one is the high-voltage EOS. A nylon spacer insulates them.
