Case 04-4198-U.S. APPLICATION OF WILLARD R. STRAUSS SLIDE WIRE ASSEMBLY ABSTRACT A slide-wire assembly has a first and a second separately movable contact arranged to engage a semicircular wire-wound resistance element or slide-wire. Clam shell halves of a molded case enclosing the slide-wire assembly are arranged to support tbe resistance element and a motor drive for one of the slide-wire contacts. The first slide-wire contact is supported on a separately movable element coaxial with a motor drive output shaft but restrained from movement therewith while providing a respective contact adjustment capability. A flexible coupling between the motor output shaft and the driven slide-wire contact enables the molded case to align the contact to apply a contact pressure in a first direction to the second slide-wire contact. Concurrently, molded ears on the concentric support for the first slide-wire contact cooperate with an adjacent inside surface of the clam shell case to provide a pressure on the second slide-wire contact in a second direction to maintain its engagement with tbe slide wire element.
