FIELD: electrical engineering.
SUBSTANCE: load step switch (1) for continuous load switching between different winding taps of step transformer (30) includes load step switch plate (2), selector (5), load switch (6). Selector (5) and load switch (6) are mounted on load stage switch plate (2). Load switch (6) includes vacuum switching lamp (7), intermediate resistor (8) and bridge switch (9). Selector (5) includes first selector brush (5.11), second selector brush (5.2) and preselector (13). First brush (5.1) of the selector is mounted on first side (3) of load step selector plate (2), and second brush (5.2) of selector and preselector (13) are mounted on the second, opposite side (4) of the load step selector plate (2).
EFFECT: reduced weight and dimensions.
