How the wallbox operates

Inside the wallbox are five pages to be flipped mannualy. Each giving 10 selections per side.
Besides this there are two fixed pages.
This totals up to 120 selections.
By rotating the pages one of the 5 switches A can be activated.

After inserting a coin on top of the wallbox, it will activate the accumulator B while passing the slug rejector C

Now a choice can be made by pressing one of the twenty selector buttons D.
The dialer starts rotating. First the number of pages flipped E are counted: at each point it will send a pulse, until it will hit the point of the opened page, the system is short circuited and no pulses are sent anymore.
Than the selected button will get recognized in the same way, on one of the next 20 points F.
After the dialler has made a full circle, the pressed button D will be released, and return in its original position.
