Abstract

The present invention relates to a high-speed controlling device, suitable for displacing a switching element between two positions with very short switching times. Said device comprises two switchable electromagnets, between which an armature, with a driven coupling to the switching element, is arranged. According to the invention, said armature contacts the first electromagnet in the first position of the switching element and contacts the other electromagnet in the second position of the switching element. In order to obtain particularly short switching times for the switching element, the armature can be firmly secured to a shaft, which is rotatably mounted about its longitudinal axis and to which said switching element is also fixed in an axially offset manner in relation to the armature.
