After the columns and rows are soldered, it's the time to connect them to the key switches. Solder a diode to each key switch pin. This will shield the pins from current, preventing them from being shortened. A diode allows current to only flow in only one direction. It features a visual indicator, a black band, that indicates the direction in which current will flow.

Replacement Case
