| Zusammenfassung: | A magnetic actuator, such as is frequently used to control the operation of electrical contacts of electromagnetic relays. The actuator has a pair of permanent magnets which retain a symmetrically-shaped armature in either of two alternative operating positions. An electromagnet is employed to aid the magnetic flux of one of the permanent magnets and to counteract the magnetic flux of the other in determining the position of the bi-stable armature. A common piece or pole is provided for the several permanent magnet circuits, which pole piece can be adjusted with respect to the armature with equal effect upon the flux flow therein. |
