Abstract

The relay incorporates a contact bridge carrier (6), a thermoplastic intermediate plate (8), an armature (9) and a coupler (10) together with two pairs of elastic beams (14,15) forming a resilient connection between the contact bridge carrier and armature. The coupler is a bolt inserted into a hole (19) at right angles to the direction of movement of the armature. The intermediate plate has lateral projections (20) on both sides for guidance of the contact bridge carrier into the housing. These serve also as points of application of the drive for an auxiliary switch (not depicted).
