Abstract
A low voltage power inverter utilizes reed switches to control a number of display tubes. The reed switches are controlled by magnetic coils or permanent magnets. The magnetic coils receive a control signal from a control circuit. The control circuit is powered by a capacitor coupled around a power lead and a capacitor coupled around a return lead. The permanent magnet is coupled to a mechanical actuator.
