Eckmiller W86a - Leaf Switches Problem
« on: January 11, 2021, 11:41:47 AM »
I have an Eckmiller w86a eq that doesn't works well.
The problem is that some of the leaf switches are not getting closed when the gear mechanism is lifting them up / stays closed when they are should be open.
What would be the best way to repair this unit?
Is it possible to get a set of new leaf switches that will be fit to replace the old ones?
Or I should design something like a relays system that will imitate the action of the original switch?

There is a tool for adjusting leaf switches, but I do not know the name for it.  I learned about it when repairing vintage electro-mechanical pinball machines, so perhaps one of the vintage gaming suppliers?

So it seems like part of the leaf switches are broken so I would like to design a relays system that will replace the original switches. I was thinking about using dual relays but there's one thing I don't know how to do.
It's easy to create the switching mode that appears on line 20 when point 51 connected to the purple pole and point 25 connected to the red pole.
Now things becomes tricky on lines 21-25 when points 51 and 52 should remain at the same switching position while point 1-5 and 11-15 should be changing according to the switching mode.
Maybe someone here having a good idea how to do this switching?
