Circuit breaker employing illuminating indicators for open and closed positions

A circuit breaker (10) includes a housing (20), a pair of separable contacts (38,40) within the housing (20), and an operating mechanism (37) having an operating handle (22) for opening and closing the separable contacts (38,40). A micro-switch (108) cooperates with the operating handle (22) and pro...

Summary:A circuit breaker (10) includes a housing (20), a pair of separable contacts (38,40) within the housing (20), and an operating mechanism (37) having an operating handle (22) for opening and closing the separable contacts (38,40). A micro-switch (108) cooperates with the operating handle (22) and provides a first output (111) when the separable contacts (38,40) are open and a second output (112) when the separable contacts (38,40) are closed. A first LED indicator (104) protrudes through the housing (20) and cooperates with the first output (111) of the micro-switch (108). The first LED indicator (104) is illuminated when the separable contacts (38,40) are open. A second LED indicator (106) protrudes through the housing (20) and cooperates with the second output (112) of the micro-switch (108). The second LED indicator (106) is illuminated when the separable contacts (38,40) are closed.
