Abstract

An on-load tap changer has: a first selector rod and a second selector rod; a load changeover-switch rod; a switch; and a transmission. The first selector rod, the second selector rod and the load changeover-switch rod are arranged collinearly. The transmission is configured to: move the first selector rod and the second selector rod during changeover from one selector contact to an adjacent selector contact in a first direction; and move the load changeover-switch rod during the changeover in the first direction and a second direction, which is opposite to the first direction, so as to actuate the switch.
