Ball Trough Opto Switches Wiring Diagram
This diagram shows the opto switches for the ball trough assembly only. See the previous page for the
individual playfield opto switches.
The ball trough opto switches are:
Switch 31 Trough Eject
Switch 32 Trough Balli
Switch 33 Trough Ball 2
Switch 34 Trough Ball 3
Switch 35 Trough Ball 4
The ball trough switches use a green LED board (pin A-i86i7-i), and a blue Photo Transistor board (pin
A-i86i8-i).
OPTO SWITCH OPERTION:
The ball rolls between the LED board and the Photo Transistor board and breaks the beam. The broken
beam 'makes' the switch.
