An electric switch includes a first and a second connection terminal for connecting the switch to an external circuit; a first switch assembly, which includes two or more electric breaker elements connected in series to one another and to the first and the second connection terminal; a second switch assembly, which includes at least one delayed electric breaker element connected in parallel to the first switch assembly. A moving actuator is made of insulating material and is associated with the first and the second switch assembly to open or close them. The moving actuator is movable between a closed switch position in which electrical continuity is established between the first and the second connection terminal, and an open position in which current flow between said terminals is prevented.

The present invention relates to an electric switch comprising a first switch assembly (1) with several electric breaker elements (2a, 2b, 2c) connected in series between two connection terminals (5, 6), and a second switch assembly (4) with a electric breaker element (3) connected in parallel to the first switch assembly (1). The second switch assembly (4) has less electrical resistance than the first switch assembly (1). The switch is configured so that the second switch assembly (4) closes in a delayed manner with respect to the closing of the first switch (1). Current interruption operations are performed with the first switch assembly (1) to facilitate arc quenching, whereas in permanent working of the switch, current flows through the low electrical resistance second breaker element (4) to reduce losses due to heating. The invention also relates to a method for controlling current flow.
