1. An electrical contactor comprising:
a first terminal having a fixed member with at least one fixed electrical contact; a second terminal; an electrically-conductive movable arm in electrical communication with the second terminal and having a movable electrical contact thereon; and actuator including a centrally mounted magnet, first and second drivable coils located either side of the magnet, a magnetically-attractable rocking armature pivotable at a point between the first and second coils, and an actuation element connected to an end of the rocking armature for actuating the movable arm; a further first terminal, a further second terminal, a further movable arm, and a further actuation element, connected to a second end of the rocking armature for actuating the further movable arm, wherein driving the first coil causes a decrease of magnetic flux in the first coil, causing a corresponding increase in magnetic flux in the second coil, the rocking armature thus latching to the second coil, thereby actuating the movable arm in a first direction, and driving the second coil causes a decrease of magnetic flux in the second coil, causing a corresponding increase in magnetic flux in the first coil, the rocking armature thus latching to the first coil, thereby actuating the movable arm in a second direction, and wherein latching the rocking armature to the first coil actuates the further movable arm in the first direction, and latching the rocking armature to the second coil actuates the further movable arm in the second direction. |
