A segmented coil has individual segments mounted on a common electromechanical switch plunger. The e.m.f. developed by the coil segments are superposed so that a reduced input voltage, relative to a continuous single coil, is capable of translating the plunger between two oppositely situated sets of switch contacts. The segmented coil structure assumes the same wire thickness as that of a prior art continuous coil operating with an input voltage of greater value. The result is retention of a small switch package for reduced voltage levels due to the fact that coil wire diameter and the number of turns may be kept the same as for a continuous coil operating with a higher voltage.
