Unique way of switching
The basis of the DC switches is formed by a double-bladed contact bridge that connects two terminal
clamps. The blade-shaped fixed contacts are clasped by the blades of the bridge. The switching takes place by turning the bridge with an insulated mandrel. The bridge and the contacts are located between two plastic discs, which together form the switch chamber.
Switching within 3ms
Springs are pre-tensioned when switching with the DC mechanism. At the end of the switch angle of 90º the built-up spring force is released in its entirely to the 2nd (inner) shaft of the switch. Because of this
construction a very high switch speed is realised which results in a very short power shut off time which is
essential for DC switching.
Switching without tension arc
The flame arc is broken off as quick as possible so that wear as a result of the flame arc is reduced to the
very minimum.
