FIELD: electricity.
SUBSTANCE: switch includes a contact assembly having an interruption chamber for each phase, which contains the first fixed contact and the second movable contact, which are mutually connected/disconnected between open and closed positions. A medium voltage switch also includes a drive for actuation of an opening and closing operation of the switch and an isolating carrying frame supporting the contact assembly and the drive. The switch includes a kinematic chain promptly connecting the drive to the movable contact, which is arranged in the isolating carrying frame.
EFFECT: improvement of insulation conditions and reduction of electrodynamic loads.
