To prevent damaging of a changeover switch due to midway stoppage that occurs for an increasing load of the cutoff mechanism of an on-load tap switching device, in the entire changeover step.

The on-load tap switching device is provided with a driving shaft 1, a wind-up case 3, an energy accumulating spring, an energy accumulating case 5, an input link mechanism 200 provided with a first lever 101 and a second lever 102, and a cut-off mechanism. While the wind-up case 3 is being moved from a position for relieving energy to a regular stop position, a feed lever 80 provided on the wind-up case 3 can be brought into contact with a second arm 15 provided on the second lever 102, and the input link mechanism 200 is used to forcedly move the energy accumulating case 5 from a regular stop position before switching to a regular stop position after switching.
