A load tap changer connected to a power source to control voltage supplied from the power source to a load includes a base assembly that includes a base element onto which multiple stationary contacts that connect to taps of a winding of an electrical control device are mounted. The load tap changer also includes a movable assembly that includes a movable element that rotates to connect at least one pair of movable contacts mounted on the movable element to a stationary contact to select a corresponding tap.
