  • Patent number: 11361925
    Abstract: A relay for assembling in terminal blocks includes an electromagnetic drive arrangement including an armature, an armature bearing spring, and a yoke. The armature is at least partially spaced from the yoke, is movably mounted, and is reduces the distance between the yoke and the armature under an effect of an electromagnetic force. The armature bearing spring applies a spring force counteracting the electromagnetic force. The yoke interacts electromagnetically with the armature to apply the electromagnetic force. A contact spring has a first contact surface and a contact arm, and the contact arm is spaced from the first contact surface and comes into contact with the first contact surface via a pressure force acting to establish an electrical connection between the first contact surface and the contact arm. An insulating element electrically isolates the armature from the contact arm and actuates the contact arm to produce the pressure force.
