摘要： A transformer switch, such as a dual voltage switch or a tap changer. The switch includes a cover, a housing, and a rotor sandwiched between the cover and the housing. The cover and housing are molded from a non-conductive plastic. An interior space of the cover includes at least one pocket within which stationary contacts are disposed. Each stationary contact is electrically coupled to one or more windings of a transformer. The rotor extends within a channel of the housing, from a top of the transformer switch to an interior surface of the cover. The interior surface includes a protrusion about which the rotor and at least one movable contact coupled thereto can rotate. The movable contact is configured to be selectively electrically coupled to at least one of the stationary contacts. For example, different stationary contact-movable contact pairs can correspond to different voltages of the transformer.

摘要： 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. The load tap changer also includes a cover assembly that includes a cover element onto which a motor that rotates the movable element relative to the base assembly is mounted.
