Patent ID: 6888269

Claim:
A magnetic linear drive for an electrical switch, comprising: a coil through which a current passes the coil and the coil having an interior in which the current produces a magnetic flux in an axial direction, having an armature which moves only at right angles to the axial direction and which has a magnetically active part whose movement path passes through an airgap within a core which passes through the first coil, or passes one end face of the core, with the magnetically active part being demagnetized or magnetized in such a manner that the magnetic flux runs parallel to the axial direction, or parallel to the axial direction but in an opposite direction, within the magnetically active part, wherein the magnetically active part can be positioned permanently in a first and second limit position and can be moved from the first limit position to a further comprising a yoke body which is arranged outside the coil, second limit position by a current.
