Abstract
A magnetic movement mechanism usable in a ground fault circuit interrupter, comprising: (i) a first permanent magnet, (ii) a second permanent magnet positioned apart from the first permanent magnet, (iii) a soft magnet positioned between the two permanent magnets, (iv) a balance frame positioned between the two ends of the soft magnet, (v) a first coil and (vi) a second coil, wherein the first coil and the second coil are arranged such that when a current passes through the first coil, a first magnetic force is generated to cause the soft magnet and the balance frame to move towards the first permanent magnet in a first direction, and when a current passes through the second coil, a second magnetic force is generated to cause the soft magnet and the balance frame to move towards the second permanent magnet in a second direction that is opposite to the first direction.
