(negative) columns. The rows need eight wires with the insulation
exposed at intervals matching the spacing of the switches; see the
above photo for details. You could also just use many short stripped
Most of the row wires will need four segments of insulation, but
you'll need two with five for the rows with the inner thumb

The exposed sections of row wire should be connected to the higher of
the pins on the switch using a diode. Be aware that diodes are
