Abstract

A flexible shunt (23) in the form of a flexible member (25) made up of a stack of electrically conductive laminations (27) each of a thickness of no more than about 0.002 inch (0.051 mm) has a moveable end (25m) secured by a moveable mount (29) to a moveable contact support of an electric power switch for movement along a linear path (17). A fixed mount (37) secures the fixed end (25f) of the flexible member (25) to a fixed conductor termination (21) spaced laterally from the moveable end (25m) along a neutral axis perpendicular to the linear path (17) of the moveable end (25m) by an offset distance (j) such that the installed length (f) of the intermediate section (25i) between the fixed and moveable ends is less than the free length (f) of the intermediate section (25i). With this arrangement the stroke (55) of the moveable end along the linear path (17) can be up to at least 1/3 and even 1/2 of the free length (f) of the intermediate section (25i) of the flexible member (25) and with very low operating forces.
