A low mass clutch in which a thin hard metal disk carried by an output shaft is placed between a driven hardened solid wheel and the outer ring of a ball bearing. The inner ring of the bearing is carried on a shaft connected to a lever. In the quiescent state of the device, the disk and wheel slide relative to each other. To engage the clutch, an electromagnet is energized, exerting a force on the lever causing the ball bearing to exert a relatively high force on the disk. In response, the wheel drives the disk with an extremely rapid angular acceleration.
