After the rows and column are joined It is now time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins from current, thus preventing them from being shortened. A diode only allows the flow of current to be in one direction, and it comes with a the black band as a visual indicator that indicates the direction current will flow.
