A first-switch-actuation-polarity power is applied to a first-switch actuation line causing the first switch to actuate and remain actuated after the applied first-switch-actuation-polarity power is removed. Actuating the first switch couples a first-switch power input line to a first-switch power output line and the first-switch power input line to the first-switch enable line. The first-switch enable line is coupled to a second-switch actuation enable line on a second switch. Second-switch-actuation polarity power is applied to the second-switch actuation line on the second switch causing the second switch to actuate and remain actuated after the applied second-switch-actuation-polarity power is removed and coupling a second-switch power input line to a second-switch power output line. |
