Abstract

PURPOSE:To prevent an overcurrent from flowing to a load circuit even if a main switching part is welded, by juxtaposing a driving plate with a driving lever and coupling this driving plate with a mobile contact maker of a sub- switching part separately from the driving lever. CONSTITUTION:When a main mobile contact of a main switching part is welded with a main fixed contact, a driving lever 75 receives force tau3 of a spring 95 and its clockwise rotation is suppressed through a cross-bar. On the other hand, since elastic force taun of a spring 82 is applied to a driving plate 91, this plate 91 is rotated clockwise with an axis 74 serving as a supporting point by elastic force taun=tau2-tau3. Simultaneously a rotary plate 56 coupled with 8 driving link 76 is rotated counterclockwise around an axis 59. Next both contacts of a subswitching part are opened by a contact arm 73 through a first rocking piece 64 and a coupling link 71. Hence an overcurrent can be prevented from flowing in a load circuit.
