I have now completed the Player 1 side. When I put it all together, I held my breath to see if the touch controls were going to give me grief again, but it seems rock solid now. So these pics show how I put the buttons together in 'layers'. First, LEDS in. Then wire LEDS. Next microswitches in. Then Touch control in and wired. You can see the touch control module is just held on a microswitch with some double sided tape. Look carefully and you will see the little squares of copper foil that make the touch switches. The connector that the touch switch goes to has three different functions to save on having even more connectors.As well as the touch switch wires, it has the earth for the buttons, and the common (positive) for the LED's which also has the resistor in heatshrink.
