A circuit breaker comprises a toggle linkage 44 having two identical pieces 46, 48 with cylindrical end portions 49 and protrusions 51. A connector 50 engages the protrusions 51 in a slot 53 thus allowing limited pivotal and sliding movement as the handle is moved from its 'off' position (as shown) to its 'on' position, in the course of which movement the portions 49 abut and roll over one another. The pieces 46, 48 have finely finished surfaces and are made to tight tolerances. Precise positioning of a hydraulic magnetic overload release mechanism 36 is effected by a clip 40. <IMAGE> |
