Abstract
The present invention relates to a switching mechanism for preventing a trip error of a manual motor starter. While using the manual motor starter, even though a latch holder (4) is incompletely released from restraint by a trip lever (3) during trip operation of the switching mechanism (1), the trip lever (3) is pushed upward to allow a restrained state of the latch holder (4) to be completely released at any event. Therefore, when implementing reset operation of the switching mechanism (1), as a latch (2) is smoothly introduced between both pins (4a and 4b) of the latch holder (4) rotated by a predetermined angle, it is possible to prevent breakage of the switching mechanism (1).
