Abstract (en)
[origin: US5315078A] A step-transformer selector has a generally cylindrical drum centered on an axis and provided with an annular array of selector contacts and, axially offset therefrom, with at least one polarity contact offset axially from the selector contacts. A selector shaft extends along the axis in the drum and rotatable about the axis to connect to selected ones of the selector contacts. A polarity switch having a pivot in the drum offset from the axis and a ring can rock in the drum on the pivot between a connecting position touching and connecting to the polarity contact and an out-of-service position offset from and out of contact with the polarity contact. A cam on the shaft engages a follower on the ring for rocking the ring from its out-of-service position into its connecting position at least once during each rotation of the shaft about the axis.
