ABSTRACT:
An electrical device such as a lamp is energized and deenergized remotely by a system in which pulses of different duration are transmitted to a receiver unit capable of discriminating between the length of the pulses in order to switch between an "on" mode and an "off" mode. A battery energizing the receiver unit is recharged by a photovoltaic cell. Advantageously associated with the battery charging circuit is an ambient lights sensing device capable of interrupting current from the battery to a load whenever the battery is being charged by the photovoltaic cell.
