Abstract
A system for monitoring switch activity using a data network includes a double pole double throw switch biased and connected to provide redundant signals from both outputs of the same switch and to convey both signals over a data network, such as a controller area network (CAN). The switch outputs may be biased to opposite polarities to improve distance between the signals.
