The flipper E.O.S_ circuits operate similar to the dedicated switch circuit. The circuits are active low and tied to
ground through the switch.
When a switch closes, the row side, (dedicated input), of the circuit activates.
The
"+"
input of the LM339 drops
below +5V therefore its output is low. Since the row (dedicated input), circuit is tied directly to ground through the
switch, the switch is considered closed by the microprocessor.
When the switch
opens, the
"+"
input to the
LM339 is above +SV, its output is high and the row (dedicated input) is inactive.
