Abstract
Abstract A physical and electrical separation of the batteries in a conventional flashlight is achieved by placing a separator plate between the batteries. The separator plate, of a non-conductive material, has a first and second side, each with a conductive coating which is not in electrical communication. A second switch means connects the two sides when placed in the "on" position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
183 words
A flashlight comprising a flashlight housing, a bulb mounted with said housing, a first battery and a second battery mounted within said housing, each battery with a first terminal and a second terminal, said first and second terminals being of opposite charge, a first switch means mounted with said housing for allowing electrical communication between said first terminal of said first battery and said second terminal of said second battery when in a first position and preventing electrical communication between said first terminal of said first battery and said second terminal of said second battery when in a second position, and circuit means mounted with said housing for making an electrical circuit comprising said second battery, said first battery, said bulb and said switch, wherein the improvement comprises: a second switch means mounted within said flashlight for separating said second terminal of said first battery from said first terminal of said second battery when in a second position and allowing electrical communication between said second terminal of said first battery and said first terminal of said second battery when in a first position.
Claim 2
Dependent Claim
183 words
A flashlight comprising a flashlight housing, a bulb mounted with said housing, a first battery and a second battery mounted within said housing, each battery with a first terminal and a second terminal, said first and second terminals being of opposite charge, a first switch means mounted with said housing for allowing electrical communication between said first terminal of said first battery and said second terminal of said second battery when in a first position and preventing electrical communication between said first terminal of said first battery and said second terminal of said second battery when in a second position, and circuit means mounted with said housing for making an electrical circuit comprising said second battery, said first battery, said bulb and said switch, wherein the improvement comprises: a second switch means mounted within said flashlight for separating said second terminal of said first battery from said first terminal of said second battery when in a second position and allowing electrical communication between said second terminal of said first battery and said first terminal of said second battery when in a first position.
Claim 3
Dependent Claim
37 words
The apparatus of claim 1, wherein said second switch means includes: a separator means mounted within said housing physically and electrically separating said second terminal of said first battery from said first terminal of said second battery.
Claim 4
Dependent Claim
54 words
The apparatus of claim 2, wherein: said second switch means is mounted with said first switch means; when said first switch means is in said first position, said second switch is in said first position; and when said first switch means is in said second position, said second switch is in said second position.
Claim 5
Dependent Claim
92 words
The apparatus of claim 3, wherein said separator means comprises: a separator plate made of non-conductive material with a first side and a second side; said separator plate is substantially covered on said first side with a conductive substance; said separator plate is substantially covered on said second side with a conductive substance; said conductive coating of said first side is not in electrical communication with said conductive coating of said second side; and said second switch means, when in said first position, electrically connects said first side to said second side.
Claim 6
Dependent Claim
35 words
The apparatus of claim 4, wherein: said separator plate is mounted within said housing such that said separator plate may move to a position within said housing allowing the insertion of batteries into said housing.
Claim 7
Dependent Claim
26 words
The apparatus of claim 5, wherein: said separator plate mounted for rotational movement of approximately ninety degrees (90°) from a separating position to a loading position.
