KEYBOARD MATRIX

Blue = PCB Trace, Black = Switch Circuit

These single pole, single throw switches can be used in a key-

board matrix and, using strapped terminals, achieve a com-

mon bus electrical configuration on a single-sided PC board.

These single pole, single throw switches can be arranged

on a single-sided PC board matrix with strapped termi-

nals to achieve an X-Y type electrical interconnection.
