Abstract
Abstract A warning system for firearms employing a linearly movable push button safety switch of the type adapted to interfere with the full rearward motion of the trigger to prohibit actuation of the firing mechanism when the switch is in a safety ON position, and an L-shaped control element connected to the switch and pivotally movable relative to the firearm in response to the linear movement of the switch, for energizing an electrical warning circuit housed in the firearm when the switch is placed in a safety OFF position in which the firearm is in an operative and potentially dangerous condition.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
86 words
A safety warning system for a firearm comprising a safety switch on said firearm linearly movable between a first safety ON position and a second safety OFF position, an electrical warning circuit, and a control element separate and distinct from and connected to said switch and pivotally movable relative to said firearm in response to the linear movement of said switch, for energizing said circuit when said switch is in said second position, and for de-energizing said circuit when said switch is in said first position.
Claim 2
Dependent Claim
86 words
A safety warning system for a firearm comprising a safety switch on said firearm linearly movable between a first safety ON position and a second safety OFF position, an electrical warning circuit, and a control element separate and distinct from and connected to said switch and pivotally movable relative to said firearm in response to the linear movement of said switch, for energizing said circuit when said switch is in said second position, and for de-energizing said circuit when said switch is in said first position.
Claim 3
Dependent Claim
42 words
The system of claim 1 wherein said control element comprises a substantially L-shaped arm, the free end of one leg of which is connected to said switch, the free end of the other leg of which is operatively associAted with said circuit.
Claim 4
Dependent Claim
49 words
The system of claim 1 wherein said control element connects a ground side of said circuit to a frame of said firearm when said switch is in said second position and disconnects the ground side of said circuit from said frame when said switch is in said first position.
Claim 5
Dependent Claim
15 words
The system of claim 1 wherein said control element is made of electrically conductive material.
Claim 6
Dependent Claim
15 words
The system of claim 1 wherein said warning circuit produces an audible signal when energized.
Claim 7
Dependent Claim
17 words
The system of claim 1 wherein said warning circuit produces a vibration of said firearm when energized.
Claim 8
Dependent Claim
15 words
The system of claim 1 wherein said warning circuit produces a visual signal when energized.
Claim 9
Dependent Claim
18 words
The system of claim 1 further comprising a microswitch responsive to said control element for energizing said circuit.
