Signal route selector and method of signal routing

The invention claims a signal routing band (14), a pair of source electrode (1) and routing with the target end (2,5,6) signal by multiple replacing loops of. Wherein the signal selecting circuit includes determining between the source electrode and volume end of the route (17), a warm-keeping is arranged on the routing substrate-processing on a transmission successful response monitoring the recording and an is any of successful failure the successful probability transmission device (18), and for acting according to the alternative power probability of success selecting to transmit power routing device.
