摘要:This invention relates to a circuit breaker switch having a cover, a housing, two copper plates, a bimetallic blade, a push button and a push rod, wherein the bimetallic blade acts as a bridging contact between the two copper plates at a rated current to conduct electricity. When there is a current overload, the bimetallic blade, because of its character, will bend and depart from the two copper plates to cut off current. The circuit may be open even if the current is not at an overload value by a user pushing the push rod inwardly to separate the bimetallic blade from the two copper plates when necessary. The contact points of the two copper plates are caused to stay in a switch-disengaging position by action of an insulating plate.
