A multiple channel stimulator for applying electrical impulses to nerves of a mammal using a single power supply to drive a plurality of channels which are selectively activated to apply electrical impulses to nerve trunks through cuff electrodes. As a channel is activated, an isolation resistor in that channel is shorted out, providing a path of low resistance in that channel compared to the other channels, insuring that any leakage current or cross currents between channels is minimized, whereby improving the performance of the stimulator.
