Abstract

A light emitting diode having a helical spring around one of its leads. The spring extends so that it has a free end which is cantilevered. As the free end of the spring moves it completes an electrical circuit intermittently lighting the light emitting diode.

Claims

1. An assembly for providing intermittent light with movement comprising;

a light emitting diode having first and second conductors extending therefrom;

a conductive, flexible spring supported on said first conductor and in electrical contact therewith, said spring having a free end extending in a cantilevered manner past said first conductor to provide a movable spring portion;

a conductive tube surrounding said moveable spring portion of said spring; and

a battery having first and second terminals, said first terminal of said battery connected to said conductive tube and the second terminal of said battery connected to said second conductor of said light emitting diode.

2. The assembly for providing intermittent light with movement of claim 1 wherein the free end of said spring extends past said conductive tube.

3. The assembly for providing intermittent light with movement of claim 1 further including an insulator surrounding a portion of said spring, but said insulator being positioned so that the free end and a cantilevered portion of said spring extend past said insulator;

a conductive tube supported by said insulator and extending past said insulator to an extent that it surrounds a cantilevered portion of said spring.

4. The assembly for providing intermittent light with movement of claim 1 wherein said battery is a wafer battery.
