1. A pacing system, comprising:
a signal generator configured to generate a pacing signal; and
an electromechanical switch having:
a substrate patterned with a plurality of contacts arranged in a circular array, wherein each contact in the circular array is configured to be in electrical communication with an electrode of a plurality of electrodes inserted into a heart of a patient, each contact of the plurality of contacts being configured to deliver the pacing signal to a respective electrode of the plurality of electrodes; and
a moving switch attached to a circular rail and configured to move along the circular rail in a circular trajectory over the plurality of contacts and to establish electrical contact with one contact only at any given time,
wherein the electromechanical switch is configured to route the pacing signal to no more than a single selected one of the contacts at any given time, so as to pace the heart using no more than a single selected one of the electrodes.
