ABSTRACT:
Disclosed herein is an illuminated screw driver or hand tool. The hand tool has a hollow handle body within which is disposed at least one light bulb, one power source and a spring for biasing the light bulb and the power source out of contact with one another. Rotation of an end cap switch moves the power source towards contact with the light bulb thereby completing the circuit and lighting the bulb. Alternate embodiments illustrate illuminated screwdrivers having one, two or three such light bulbs and power sources and spring means for biasing each bulb and power source out of contact with one another. In the embodiment having three light bulbs there is provided a mechanism for selectively turning on one, two or all three of the light bulbs.
