Abstract
A power saving device for use in a power supply circuit has an electronic switching element which is turned on when a pushbutton normally open type switch is closed to actuate a DC-DC converter and a fully electronic control system which forces the electronic switching element into the non-conduction state after a predetermined time interval, to interrupt the connection of a low-voltage power source to the DC-DC converter.
