Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 128 words
The combination of a primary circuit and a secondary circuit wherein the completion of said primary circuit changes the state of said secondary circuit, comprising: a main power source; a connector device; conductive means connecting said power source to said connector device; a power inlet means arranged to be selectively detachably connected to said connector device; conductive means connecting said power inlet means to said primary circuit so that said primary circuit may be energized; a power source for said secondary circuit; a switch in said secondary circuit in series with said secondary circuit power source and switch actuating means carried by said power inLet means and responsive to the connecting and disconnecting of said power inlet means with said connector device to open and close said switch.
Claim 2
Dependent Claim 128 words
The combination of a primary circuit and a secondary circuit wherein the completion of said primary circuit changes the state of said secondary circuit, comprising: a main power source; a connector device; conductive means connecting said power source to said connector device; a power inlet means arranged to be selectively detachably connected to said connector device; conductive means connecting said power inlet means to said primary circuit so that said primary circuit may be energized; a power source for said secondary circuit; a switch in said secondary circuit in series with said secondary circuit power source and switch actuating means carried by said power inLet means and responsive to the connecting and disconnecting of said power inlet means with said connector device to open and close said switch.
Claim 3
Dependent Claim 78 words
The circuits as defined in claim 1 wherein said switch actuating means comprises a reciprocable plunger carried by said inlet means in position to extend beyond the front wall of said inlet means when said inlet means is disconnected from said connector device and arranged to be depressed when said power inlet means and said connector device are connected, whereby the contacts of said switch may be engaged and disengaged by the extension and retraction of said plunger.
