Abstract

Switching apparatus of a load selector of a tapped transformer comprises stationary contacts (1, 2, 3, 4) arranged in a circle, movable contacts displaceable along the circle and control cams (11, 12; 21, 22; 31, 32; 41, 42) of insulating material disposed adjacent the stationary contacts (1, 2, 3, 4). The movable contacts comprise contact rollers (6, 7, 8) arranged to roll along the stationary contacts (1, 2, 3, 4) and at least one roller (61, 62, 71, 72, 81, 82) of insulating material arranged adjacent a respective one of the contact rollers (6, 7, 8). The control cams (11, 12; 21, 22; 31, 32; 41, 42) are so arranged that during a switching operation the rollers (61, 62, 71, 72, 81, 82) of insulating material run onto the control cams (11, 12; 21, 22; 31, 32; 41, 42) and cause the contact rollers (6, 7, 8) to lift from the stationary contacts (1, 2, 3, 4) before the contact rollers (6, 7, 8) are able to roll off the stationary contacts (1, 2, 3, 4). <IMAGE>
