ABSTRACT:
A flashlight senses when it is picked up, and then automatically turns on. When the flashlight is released or set back down, it automatically turns off. Touch or contact sensors sense the touch of a human hand, causing a circuit in the flashlight to switch on a light source, such as an LED. The flashlight is advantageously designed so that when grasped or picked up, the fingers of the user's hand lay over touch sensors. Various types of touch sensors may be used. The touch sensors may operate electrically, and without any movement, or moving parts.
