  • Patent number: 9548173
    Abstract: An electrical contactor has first and second terminals; a movable arm connected to the second terminal; and an actuator. The actuator has a magnet, first and second coils having a common connection and located either side of the magnet, a magnetic rocking armature pivotably attached between the coils and an actuation element connected to the first end of the rocking armature for actuating the movable arm. Driving the first coil causes a demagnetization of the first coil and a corresponding increase in magnetic flux in the second coil, latching the armature to the second coil and moving the movable arm in a first direction. Driving the second coil causes a demagnetization of the second coil and a corresponding increase in magnetic flux in the first coil, latching the rocking armature to the first coil and moving the movable arm in a second direction.

A shuttle element (25) slidably extending through the housing (17) has provided at each end a disc (30, 31) the inner surfaces of which control the movement of a pair of push-rods (42, 43), also extending through the housing (17), which push-rods (42, 43) are bearable on opposite sides of the retaining blocks (20, 21). Reciprocal movement of the shuttle element (25) causes the same movement of the push-rods (42, 43) to move the movable fiber array (19) between its two switch positions. Movement of the shuttle element (25) is caused by the selective energization of two electromagnets (50, 51) mounted in opposite walls (40, 41) of an hermetically sealed outer housing (18).
