Abstract
PURPOSE:To obviate the need to mount excess parts to electric machine by working operating roller to be mounted to electric machine as a switch. CONSTITUTION:When the bradker 13 is drawn out, it can be drawn out by pulling out the taking-in and out mechanism for electric machine. In this case, the operating roller 16 slides toward the operation terminal side of the operating cam 25 in contrast with the time of insertion and the pulling force of the spring 29 moves upward the shutter plate 23 through the operating cam 25 and the slider 23. Furthermore, when when finishing the drawing of the breaker 13, the shutter deivce comes back and the through holes A and B of the partition plate 20 for disconnected line are closed by the shutter plate 24. Thus, the switching operation of the shrtter plate can be by means of the operating roller 16 of the breaker 13.
