The contacts are connected with the taps of the winding of the step transformer. In the first level (I) of the fine selector (FW) the uneven-numbered contacts (1,3,5) are arranged in opposite pairs, as shown, and in the second level (II) the even-numbered contacts (2, 4) and another contact (K) are arranged in opposite pairs. Tel bridges (Br1, Br2) of the fine selector and those (Br3, Br4) of the coarse multi-selector (GW) are connected together so that they can move. |
