ABSTRACT:
A mechanism is provided for operating an electrical switch of the type having a set of contacts electrically connected to the tapped windings of an inductor or transformer, and a tap changing mechanism for electrically connecting various contacts in response to the rotation of a shaft. The electrical switch is mounted onto the base of the inductor or transformer and the operating shaft of the switch is connected to a flange wheel. Another flanged wheel carried by the base, is in connection with a prime mover on the exterior of the transformer or inductor. One or two bowden cables are connected between the two flanged wheels with the outer portions of the bowden cable held fixed relative to the base and the inner portion of the bowden cable connected to the flanged portion of the wheels in such matter that relative motion between the inner and outer portions of the bowden cable induces rotation of the wheels. Thus, the switch is rotated in direct response to the prime mover.
