The invention relates to a coil device as well as an electromagnetic repulsion mechanism and a quick switch adopting the coil device. The quick switch comprises the electromagnetic repulsion mechanism, and the electromagnetic repulsion mechanism comprises the coil device. The coil device comprises at least one helical coil and a coil skeleton, wherein the coil skeleton is provided with a mounting surface for placing the end face of the coil, a first insulated filling body is arranged in gaps between adjacent circles of the coil, and the first insulated filling body fixes the coil onto the mounting surface by curing. The first insulated filling body fixes the coil onto the mounting surface, so that the strength of the coil device is relatively high; and the impact load subjected by the coil device is borne by the coil and the first insulated filling body together, so the coil is unlikely to deform or damage and the coil device is also unlikely to damage.
