Abstract

A stepping switch connected rigidly to the active part (7) of a stepping transformer, the stepping switch having a cylindrical oil reservoir (1, 100) containing a load switching insert (2). An intermediate flange (11, 111), which can move axially in the oil reservoir (1, 100) or in the head flange (10, 101), is connected loosely, but not detachably or rotatably, to the oil reservoir and to the head flange with an O-ring seal (13, 131) placed between them. In this arrangement, the intermediate flange (11, 111) can be attached, in the first case, to the head flange (10) seated on the flange opening of the stepping transformer and, in the other case, to the upper end of the oil reservoir (100). <IMAGE>
