And this current will be transferred to a large capacitor for storage. His design incorporated a dry cell battery, a small electric bulb, and a rudimentary switch mechanism. An L-shaped spring returns the handle to its original position after each engagement. Cyansky Powered By Freasy Technology Co., Ltd. All Rights Reserved. She had two sons, Stephen and Christopher, and one daughter, Jackie, who would come to know Tony as their stepfather.[2]. The flashlight relies on the physics of light to function.
