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.
