Abstract
PURPOSE: To supply an electrical power to a load with a simple operation and effectively by outputting with closing an electrical power source switch of a loading device and by performing a reset of a protective circuit with opening the switch.
CONSTITUTION: At a normal case by closing a switch 6 transistors Tr2 and Tr3 become to "on" and an electrical power of a battery B is effectively supplied to a load 5. In case when a short circuitting failure happens on the load 5 a thyristor CR2 becomes to "on". For this sake transistors Tr2, Tr3 become to "off" and a supply of an electrical power to the load 5 is stopped. Continuing to these conditions by operating a switch 6 to "off" the thyristor CR2 becomes to "off" and a reset of a protective circuit 1a is accomplished
