ABSTRACT:
An improved firing circuit for rocket launchers and the like which includes normally open switch between the power source and the firing selector switch and an oscillating grounding switch. The grounding switch and the firing selector switch are simultaneously operated by a rotary solenoid or the like and are connected by a ratchet arrangement so that oscillatory motion of the grounding switch causes rotary motion of the firing selector switch. The normally open switch is closed to apply power through the selector switch only near the end of each increment of rotation.
