Abstract

A circuit breaker mechanism includes an operating part and an on-off switch part. The operating part includes a handle, a shaft, and a mechanism member. The handle is engages the shaft for rotation. The mechanism member moves responsively to rotation of the handle. The on-off switch part includes a switch lever, a switch shaft, and a spring. The switch lever is supported for rotation by the switch shaft between on and off positions. The spring biases the switch lever to one of the positions. The mechanism member has a portion engagable with a portion of the switch lever to control movement of the switch lever. The portions of the mechanism member and the switch lever are configured to permit assembly of the on-off switch part separate from the assembly of the operating part and engagement of the portions of the mechanism member and the switch lever subsequent to assembly of the on-off switch part.

Dependent claims

A circuit breaker on-off switch mechanism comprising:

an operating part comprising an operating handle, a handle shaft, and a mechanism member, the operating handle engaging the handle shaft and being rotatable with the handle shaft as a fulcrum, the mechanism member being interconnected to the operating handle within the operating part to move responsive to rotation of the operating handle;
and
an on-off switch part comprising an on-off switch lever, an on-off switch shaft, and a main spring, the on-off switch lever is supported for rotation by the on-off switch shaft between a circuit on position and a circuit off position, the main spring biases the on-off switch lever to rotate from one of the on and off positions to the other of the on and off positions;
the mechanism member has a portion engagable with a portion of the on-off switch lever to control movement of the on-off switch lever responsive to rotation of the operating handle, the portion of the mechanism member and the portion of the on-off switch lever being configured to permit assembly of the on-off switch part separate from the assembly of the operating part and engagement of the portions of the mechanism member and the on-off switch lever subsequent to assembly of the on-off switch part.
