A total of eight pushbuttons can be connected, corresponding to four accessories
(turnouts, signals, etc.), each of which has two positions (straigh or diverging track,
red or green, etc.).
The buttons must be connected to
connectors 1 and 2 (fig. 3). Figure 4
shows the connection in detail. One pin of
each button must be connected in
connector 2 to the specific output that has
to be controlled (black wires in the
figure), while the other terminal must be
connected to connector 1 together with all
the other buttons of the board (red wires in the figure). The two terminals of
connector 1 can be used indifferentl (the one with the solid line or the one with the
