ABSTRACT:
An electromagnetic relay has a bar-shaped armature which is mounted at one end at a coil flange in a carrier comprised of insulating material, in which center contact blades are also mounted at opposite sides of the armature such that movement of the armature is transmitted to the contact blades through the carrier, thus eliminating the plunger which is normally present for contact actuation. The offset positioning of the contact blades with respect to the armature in the carrier causes friction which substantially prevents damaging impact of the contact pads of the contact blades with respectively mating stationary contact pads.
