摘要:A transformer tap changing switch including a rotary contactor shaft supportingspaced apart radially extending arms having roller contactor sets mounted thereon andyieldably biased into engagement with adjacent ones of an array of elongated cylindricalrod contacts supported between spaced apart switch frame plates. Each of the rodcontacts includes a centrally disposed lug or blade type terminal located between theroller contactor assemblies and spaced sufficiently from each such that current flowalong the rod contact elements between the terminal portions and the rotary switchcontactors establish counteracting magnetic force fields which substantially cancel eachother and eliminate any forces acting on the rotary contactor assembly. The switchincludes a manually actuated lever for rotating the contactor shaft and which is providedwith a switch position locking mechanism including a spring biased pin which projects intoa selected hole in a position locking plate member.
