Abstract (en)
[origin: US6234106B1] A position indicator for a motor drive for actuating a step switch, tap changer, or dipping coil, has a display board having front and back faces and a first circular array of symbols on the front face corresponding to individual switching phases traversed during changeover of the motor drive from one operational position into another neighboring operational position. A first shaft extending through the board centrally of the first array and defining a first axis carries a pointer at the front face rotatable about the first axis through positions aligned with the symbols. A second circular array of symbols on the front face is associated with individual possible stationary operational positions of the step switch, the tap changer, or the dipping coil. A second pointer shaft projecting through the board centrally of the second array and defining a second axis carries a second pointer at the front face rotatable about the second axis through positions aligned with the symbols of the second array. Respective trailing pointers pivotal on the second axis and not driven by the second shaft flank the second pointer and have entrainment formations engageable therewith. Thus as the second pointer moves and engages either of the pointers it displaces same. A gear mechanism on the back face connects the second shaft to the first shaft for movement of the second pointer angularly codirectionally with the first pointer between adjacent symbols of the second display on rotation of the first pointer through 360°.
