Abstract
In relation to a circuit breaker, a left-side accessory switch storage section and a right-side accessory switch storage section are provided in a breaker case . A contact point of an ancillary switch provided in one of the accessory switch storage sections is opened or closed in conjunction with an output protrusion formed on an open-close lever of an open-close mechanism section on the main unit. A contact point of an alarm switch provided in the remaining accessory switch storage section is opened or closed in conjunction with an alarm output plate which operates in association with tripping action of the breaker. The output protrusion is caused to oppose an operation lever of an ancillary switch which is formed into a symmetrical bifurcated shape and which is provided in the accessory switch storage section. The alarm output plate constitutes a pivotal lever coupled to a toggle shaft of the open-close mechanism section. An output protrusion provided at the extremity of the pivotal lever is caused to oppose an operation lever of the alarm switch provided in the accessory switch storage section.
