Abstract:

A circuit breaker is provided of the push-pull type for use in the cockpit of an aircraft wherein the plunger of the circuit breaker is illuminated upon the opening of a circuit. The illumination immediately attracts the pilot's attention so that corrective action can be taken. A bi-metallic strip bows when it is heated due to overloading of the circuit causing the plunger to be extended and to complete a secondary circuit to a light located within the head of the plunger. A number of the circuit breakers are electrically interconnected to provide a visual indication to the pilot that a fault condition has occurred in one of the monitored aircraft circuits. In addition, an indicator is available to inform the pilot that a second fault condition has occurred subsequent to the occurrence of a first fault condition while the first fault condition remains.
