Wiring Diagram for the Ball Trough Assembly Opto Switches
This diagram shows the opto switches in the Ball Trough Assembly only. See page
3-21
for the individual
playfield opto switches.
The Ball Trough Assembly opto switches are:
Switch #41 Trough Eject
Switch #42 Trough Ball 1
Switch #43 Trough Ball 2
Switch #44 Trough Ball 3
Switch #45 Trough 8all4
The Ball Trough Assembly opto switches use a green Ball Trough LED board (PIN A-18617-1), and a
blue Ball Trough Photo Transistor board (PIN A-18618-1).
OPTO
SWITCH
OPERATION:
The ball rolls between the Ball Trough LED board and the Ball Trough Photo Transistor board and breaks
the beam. The broken beam 'makes' the switch.
