ABSTRACT:
A magnetic relay having a core, coil, an armature with a pair of dielectric cards, a plurality of pairs of contact points and a contact spring, has been found. One of said dielectric cards pushes or releases the contact spring according to the electric current flowing in said coil and said pairs of contact points are closed or opened. The structure of the present relay is so simple that mass production and improvement of accuracy of the relay can be easily accomplished.
