Abstract
A magnetic system for an electromagnetic relay comprises at least two iron pieces extending in parallel through the entire length of one common coil , each iron piece being part of its own magnetic circuit for operating an armature which is disposed in this magnetic circuit to operate ah associated contact system. The spacing between the iron pieces inside the coil is substantially smaller than the largest cross-sectional dimension of each iron piece in order to make maximum use of the magnetic flux produced by the coil with minimum loss and minimum stray flux.
