KEYHOLE LIGHT
First Claim
1. A lighting fixture comprising means including a sliding pin for making a mechanical engagement with an outer storm or screen door, electrical contact means having a V-shaped end in contact with a flat edge to provide a rubbing contact operated by said sliding pin near the start of pin travel for opening and closing an electrical circuit, said contact and pin being oriented so that extended pin travel does not further effect any contact operation, said pin being long enough to preclude a closure of said electrical circuit unless said door is fully open, thus precluding closure if said door is slightly ajar, and lamp means including a bulb positioned adjacent a keyhole and operated when said circuit is closed.
