ABSTRACT:
The apparatus for testing electrical switch matrices includes a potential selector (30) for receiving and applying a voltage (28) to a predetermined input (101-106) of each of the plurality of electrical switches (12), a controller (15) for receiving and applying signals to the plurality of electrical switches (12), and a combiner (36) responsive to an output (22) of each of the plurality of electrical switches (12). The controller (15) selects electrical paths (16) associated with each of the switches (12) which are in communication with the predetermined inputs (101-106) of each of the switches. The output (38) of the combiner (36) indicates whether at least one of the selected electrical paths (16) failed.
