Click to expand

Install all switchs:

Connect rows

Trim the diode anode to approximately 5mm

Solder the first, and the second

This is what it looks like from the side:

This method eliminates the need for insulation

Then just repeat it:

Connect the matrix to the board as follows:

Solder the board-side wires first, then you can get creative with the routing

Done
