Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 107 words
An improved circuit breaker including a three position switch assembly and having an illuminated overload indicator, the improvement comprising: A. battery means mounted on said circuit breaker; B. secondary switch means activated by the movement of the lever of said circuit breaker so that said secondary switch means is closed when said lever is in the conventional overload position and open in the other two positions; and C. conductor means mounted on said circuit breaker and connecting said battery to said indicator having said secondary switch means in series so that the circuit may be interrupted and reestablished thereby illuminating said indicator when an overload condition occurs.
Claim 2
Dependent Claim 107 words
An improved circuit breaker including a three position switch assembly and having an illuminated overload indicator, the improvement comprising: A. battery means mounted on said circuit breaker; B. secondary switch means activated by the movement of the lever of said circuit breaker so that said secondary switch means is closed when said lever is in the conventional overload position and open in the other two positions; and C. conductor means mounted on said circuit breaker and connecting said battery to said indicator having said secondary switch means in series so that the circuit may be interrupted and reestablished thereby illuminating said indicator when an overload condition occurs.
Claim 3
Dependent Claim 51 words
The device set forth in claim 1 wherein said secondary switch means includes one laminated conductor mounted on said lever cooperating with another laminated conductor on the inside of the cap of said circuit breaker so that both of these conductors physically coincide when said lever is in the overload position.
Claim 4
Dependent Claim 28 words
The device set forth in claim 2 wherein said lever includes an end and said indicator means includes an LED device mounted on the end of said lever.
Claim 5
Dependent Claim 34 words
The device set forth in claim 3 further including a battery compartment housed within said circuit breaker and said conductor means further including cooperating mating contact pads completing the circuit of said conductor means.
