Реферат: An electric power switch drive braking unit is particularly for HV switches with power battery drive systems. In order to provide a simple, non-expensive braking unit that meets all specification demands a braking disc is rigidly located on the drive shaft rotated by the power battery. The protruding cams arranged on the disc make contact with a stopcrank, arranged on a rotating spring-loaded element, in the final stage of a switching movement. After the completion of the rotation path, the contact between the cams and crank is broken, and the latter is returned to its initial or starting position by the action of spring force. The spring-loaded element is specifically formed from a rubber spring.
