ABSTRACT:
A cylindrical step selector for stepped transformer has its contact rings supported by horizontal conductors which extend out of the insulated cylinder surrounding the shaft which can displace the contact bridge along such ring and into engagement with a fixed contact. Externally of the cylinder, the conductors are aligned one above the other so as to be engageable by a pair of clamping bars which provide additional bracing. The conductors may be turned upwardly along these bars and held to the latter by straps.
