The embodiment of the invention disclosed herein is directed to a solid state switch structure which includes first and second spaced apart saturable magnetic cores. The cores are saturated in the presence of a magnetic field of given strength. A drive wire passes through both cores, and a pair of sense wires pass through both cores but are wound thereabout in opposite directions. The saturation of one of the magnetic cores causes an output signal from one sense wire of one polarity and an output from the other sense wire of the opposite polarity. Moving the magnet from adjacent one saturable magnetic core to adjacent the other saturable core reverses the polarity of the output signals at the sense wires. While moving the magnet between saturable magnetic cores a point is reached whereupon no output signal is sensed at either sense wire. |
