Abstract

In a transfer switch for alternating current two electric switching devices of hybrid type are adapted to establish and break, respectively, a current path between a load and an alternating current supply each for transferring the supply of the load with electric power from one alternating current supply (5) to the other (6). The switching devices have components (15-18) blocking in at least one direction for establishing a temporary current path therethrough when breaking the current path through the switching device and enabling an arc-free completion of the breaking. A control unit (20) is adapted to control a movable part (4) to carry out one single mechanical movement for opening one of the switching devices and closing the other for changing the alternating current supply to the load.
