ABSTRACT OF THE DISCLOSURE A miniature relay having an electromagnet assembly including a coil carried by a magnetic frame member which assembly is supported on a non-magnetic coil support member which in turn is secured to a header containing an arrangement of stationary and movable contacts and terminal pins. The magnetic frame member includes a core extending through and slightly beyond the coil and a pole piece outwardly adjacent the coil. An armature is held in position by the cooperation of spaced-apart holding elements depending from the electromagnet assembly which saddle a recess area in the armature, and a return spring carried by the header continuously urges the armature into saddle defined by the holding elements. The pull- in force of the electromagnet is enhanced by a mating tab and notch con- figuration of the pole piece and armature or by an end portion of the pole piece disposed to present increased surface area facing the armature.
