Abstract

Electromagnetic, monostable, small relay has a rocker armature arranged between a base plate and a coil, the armature being mounted with its middle segment at the end of an L-shaped yoke, and forming a working air gap with a second yoke. Contact springs are connected with the armature, which work together with fixed contacts anchored in the base. A resetting spring is connected with the armature and prestresses the armature into a rest position on the first yoke. For stabilization of the construction, and for separation between a contact chamber and a coil chamber, a base body is provided with an H-shaped cross-section, which overlaps the base plate in an interleaving manner, and which forms supports for the terminal pins of the base plate on both sides of the armature. In this way, a monostable relay is created, which can have any of conventional soldering pin terminals, SMT terminals, or press-fit terminals.
