A DC voltage circuit interrupter comprising: a stationary contact arm formed as a substantially flat elongated piece having a first end and a second end; a stationary contact positioned on an under side of and toward a middle portion of said stationary contact arm; a stationary magnet positioned on an upper side of and toward the middle portion of said stationary contact arm, said stationary magnet generating a stationary magnetic field; a moveable contact arm formed as a substantially flat elongated piece having a first end and a second end; a moveable contact positioned on an upper side of and toward a middle portion of said moveable contact arm; a moveable magnet positioned on an under side of and toward the middle portion of said moveable contact arm, said moveable magnet generating a moveable magnetic field; wherein the stationary magnet field and the moveable magnetic field are additive with respect to each other; said moveable contact arm displaceable along a linear path such that said moveable contact physically contacts said stationary contact in a closed position, and said moveable contact does not physically contact said stationary contact in an open position; a first arc extinguisher positioned below the first end of said stationary contact arm; a second arc extinguisher positioned below the second end of said stationary contact arm; wherein when an arc occurs between said stationary contact and said moveable contact, the magnetic fields urge the arc off of the contacts and onto the stationary contact arm and moveable contact arm and toward either said first or second arc extinguisher depending on a polarity of the DC voltage. a stationary contact arm formed as a substantially flat elongated piece having a first end and a second end; a stationary contact positioned on an under side of and toward a middle portion of said stationary contact arm; a stationary magnet positioned on an upper side of and toward the middle portion of said stationary contact arm, said stationary magnet generating a stationary magnetic field; a moveable contact arm formed as a substantially flat elongated piece having a first end and a second end; a moveable contact positioned on an upper side of and toward a middle portion of said moveable contact arm; a moveable magnet positioned on an under side of and toward the middle portion of said moveable contact arm, said moveable magnet generating a moveable magnetic field; wherein the stationary magnet field and the moveable magnetic field are additive with respect to each other; said moveable contact arm displaceable along a linear path such that said moveable contact physically contacts said stationary contact in a closed position, and said moveable contact does not physically contact said stationary contact in an open position; a first arc extinguisher positioned below the first end of said stationary contact arm; a second arc extinguisher positioned below the second end of said stationary contact arm; wherein when an arc occurs between said stationary contact and said moveable contact, the magnetic fields urge the arc off of the contacts and onto the stationary contact arm and moveable contact arm and toward either said first or second arc extinguisher depending on a polarity of the DC voltage. <EOS>
