Abstract
An electric switching device for alternating current comprises two contact members and a component (21, 22) having ability to block current in at least one direction and conduct current in at least one direction therethrough. It also comprises a unit (14) adapted to control the first contact member to open for transferring the current to the component when this is in or going into conducting state and then the second contact member to open when the component is in a state of blocking current therethrough for breaking the current through the switching device. It also comprises a movable part (4) and a unit (14) adapted to control this part to carry out one single mechanical movement for opening or closing the two contact members.
