Abstract
An overload protection switch with reverse restart switching structure, particularly to one that has a molded-case circuit breaker which adding a lampshade parallel stagnation position for overload indication, and when resetting, needs to press back to the RESET for reconfirmation; due to the stagnation position and reverse restart structure, it can avoid repeating the reset action, preventing the reduction of the life of the overload protection switch and repeated exposure or the misjudgment and then resetting of electrical products that have been overloaded and tripped and then overload again then results in causing dangerous; also, the lampshade can be completely tripped even when the lampshade is suppressed, and prevent the danger of repeated tripping during overload.
