Electromagnetic relay

A polarized magnetic relay has a base body, an armature, an envelope that encompasses insulating material, a coil, a core and a bar-shaped permanent magnet. The base plane is defined by the bottom side of a base body. The armature is arranged between two contact springs that lie parallel to each other in a common plane. Two transverse terminal webs, which have their sheet metal plane extending parallel to the base plane, extend out of the envelope in the area of the rotational axis of the armature and these terminal webs are respectively connected with a fastening tab that has its sheet metal plane extending perpendicular to the base plane. The contact springs exhibit two spring arms and a connecting web, respectively, which has its sheet metal plane extending perpendicular to the base plane. The spring arms exhibit a contact making part and a part that is embedded in the envelope. The part that is embedded in the envelope emerges into the connecting web.

Polarized electromagnetic relay

An electromagnetic relay has a magnet system, a base, a movable contact element, stationary contact elements and contact terminal elements. The base is formed by a printed circuit board arrangement. A first printed circuit board of the printed circuit board arrangement thereby faces toward the magnet system, and a second printed circuit board of the printed circuit board arrangement forms a bottom side of the relay. Each of the two printed circuit boards has interconnects. The movable contact element is actuated by an armature and is arranged between the two printed circuit boards. An actuation element that transmits the movement of the armature onto the movable contact element has a pin-shaped end section projecting through a recess in the first printed circuit board. The contact terminal elements are pin-shaped and project through congruent recesses in the two printed circuit boards.

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.
