1. An actuator which can be actuated electronically from a switched-off position to a switched-on position, comprising:
a coil (33) for generating a magnetic field; a magnetically conductive actuator sleeve (37) surrounded by said coil (33); a magnetic flux guiding element (53) arranged stationary with respect to said actuator sleeve (37); an armature (43) mounted for axially sliding movement within said actuator sleeve (37); said armature having at least two axially extending, parallel, axially offset, magnetic flux conducting profiles (99, 101); and said actuator sleeve (37) comprising at least two magnetic flux conducting parallel passage areas (95, 97) of different cross-section and complementary to and facing said magnetic flux conducting profiles of said armature for permitting respective ones of said conducting profiles of said armature (43) to slide along respective ones of said parallel passage areas; said at least two axially extending, parallel, axially offset, magnetic flux conducting profiles (99, 101) contacting said at least two magnetic flux conducting passage areas (95, 97) in the switched-off position as well as in the switched-on position. |
