く、この接合部が破損するおそれがあった。In such a conventional multi-pole type circuit breaker for wiring, when the handle 21 is tilted to the ON side, the force of the spring 25 is transmitted to the fingers 22, 23 via the resin plate 24, and the fingers 22, 23 is strongly pressed toward the fixed contact. However, in such a structure, the contact pressure varies between the electrodes due to the twisting of the fingers 22 and 23, and there is a possibility that some electrodes may have insufficient contact pressure. That is, if the finger 22 is located closer to the fixed contact side than the finger 23 due to the deformation due to the twist, the contact of the finger 23 with the fixed contact is blocked by the finger 22, and the contact pressure of the finger 23 is the contact pressure of the finger 22. Will be smaller than. In the conventional multi-pole circuit breaker for wiring, the metal fingers 2
The twisting stress was likely to be concentrated on the joint between the resin plates 23 and 23 and the joint could be damaged.
