Abstract
A relay has a coil form, preferably made of ceramic, with a winding and a U-shaped core yoke, whose ends are bridged by a flat armature. The armature actuates an insulating switching spring, made of ceramic or a similar material, which bridges two counter-contacts with a bridge contact on its movable end. The relay can be used at high ambient temperature, even with a very small construction.
