Abstract
Solid state control circuitry for driving an electromagnetic armature of a battery operated electric stapler. The armature is activated by a trigger signal generated by a trigger switch which discharges an energy storage device through the armature. Energy is rapidly replenished in the energy storage device following its discharge; but if a subsequent trigger signal is not forthcoming, the control circuit reverts to a quiescent state, thereby reducing power consumption.
