Abstract
Abstract A magnetically actuated illuminating warning device for conventional circuit breakers of the type that have a switch assembly with three possible positions for its switch lever. A battery powered illuminating device is mounted in the vicinity of the breaker and the illuminating circuit is interrupted by a magnetically actuated switch that is closed when a permanent magnet mounted on the switch lever comes within a predetermined distance. The position of the magnetic switch is selected so that it is actuated or closed when the switch lever is in the overload position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
92 words
In a circuit breaker of the type that includes a switch assembly having a switch lever with three positions, on, off and overload, the improvement comprising: A. illuminating warning means, including battery means for powering itself. B. magnetic switch means in series and normally interrupting the operation of said warning means and said magnetic switch means positioned in the vicinity of said switch lever, and C. permanent magnet means rigidly mounted on said lever and positioned to effectively activate said magnetic switch means when said switch lever is in the overload position.
Claim 2
Dependent Claim
92 words
In a circuit breaker of the type that includes a switch assembly having a switch lever with three positions, on, off and overload, the improvement comprising: A. illuminating warning means, including battery means for powering itself. B. magnetic switch means in series and normally interrupting the operation of said warning means and said magnetic switch means positioned in the vicinity of said switch lever, and C. permanent magnet means rigidly mounted on said lever and positioned to effectively activate said magnetic switch means when said switch lever is in the overload position.
Claim 3
Dependent Claim
20 words
The improvement set forth in claim 1 wherein said illuminating means includes an LED in series with said battery means.
Claim 4
Dependent Claim
25 words
The improvement set forth in claim 2 wherein said permanent magnet means include a sleeve member for readily attaching said magnet means to said lever.
Claim 5
Dependent Claim
98 words
In a circuit breaker of the type that includes a switch assembly with three possible positions, on, off and overload, the improvement comprising: A. a magnetized switch lever in said switch assembly; B. magnetic switch means, of the normally open contacts type, mounted close to said lever and positioned so that said contacts close when said switch lever is in the overload position. C. illuminating warning means, including battery means for powering itself, and connected in series with said magnetic switch means so that said warning means is activated when said switch lever is in the overload position.
