Abstract: A circuit is disclosed for switching power to a battery operated device, particularly a portable radio transceiver. The power control circuit uses an on/off switch that remains in a fixed "on" or "off" position instead of using a momentary push button switch. The circuit allows powering down the radio to prevent deep discharging of the battery even though the switch remains in the "on" position. Also, the circuit allows the radio to continue to be powered up under microprocessor control after the switch is placed in the "off" position.
