Abstract
An intrinsically safe battery circuit for connection between a battery and a load, such as a hand held transceiver, referred to as 'HT's'. The circuit includes a minor current path through a switching transistor and a major current path through a SCR. The circuit is a hybrid circuit which includes an integrated circuit timer which provides a delay in establishing the major current path subsequent to the minor current path being established, and mounts on a small printed circuit board.
