Abstract:
A mechanical switching device (1) comprising a base member (3), at least one pair of elongated conductor members (5) mounted on the base member, each conductor member comprising a conductor end (7), wherein the conductor ends of the pair of conductor members are separated by a gap (9), a middle member (11) mounted on the base member, a switch member (13) comprising a stationary part and a movable part, the movable part comprising a conductor bridge. The stationary part comprises a protruding member protruding away from the direction of displacement of the conductor bridge, wherein the base member, the conductor members, the middle member and the stationary part of the switch member are attached together by means of at least one attachment arrangement formed in the base member, the middle member and the protruding member.
Abstract:
An electromagnetic contactor that is designed for error-free assembly. The housing includes a contactor carrier interference that fixes the orientation between the housing and contact carrier. Orientation between the contact carrier and the armature is fixed by an offset elliptical joint. Pole shader interferences fix the orientation between the coil cover subassembly, the armature and the magnet. Shoulders located on two of four base legs fix the orientation between the housing and the base. The base includes a rail spring, spring catches, upper and lower catches that allow the contactor to be mounted on a DIN rail without using tools.
Abstract:
The invention relates to an electromagnetic switching device, in particular a contactor, comprising a switching device housing (2) and a plug-in module which can be inserted into the latter and which contains a coil form (12) for a coil. A tripping element (60) is mounted on a housing section (40) of the plug-in module (4). Said element is designed to mechanically actuate the contact unit (30) of an electric switch (24) for producing an economy connection. The switch (24) is mounted on a support structure (printed-circuit board (22)) that is located in the plug-in module (4), with a supporting contour (70) of said switch adjoining a bearing contour (72) of the housing section (40).
Abstract:
An electromagnetic relay in which a flange (2b) of a spool (2) is disposed inside a case at an opening of the case and a fixed terminal (11) is attached to the spool (2). The problem of dust produced while the fixed terminal (11) is attached is solved and the fixed terminal (11) (especially the portion where a fixed contact (10) is provided) is attached in a good state. Projections (11e, 11f) extending from a fixed terminal (11) are forced into through holes (2e, 2f) made in the flange (2b), and the vicinity of the fixed contact of the fixed terminal (11) is engaged with an engagement part (2f) formed on the other flange (2a), thereby attaching the fixed terminal (11).
Abstract:
The inventive relay has a base body in the form of a coil body (1), said base body supporting a core (16), a yoke (20), an armature (22) and a contact spring (23) which is connected to the armature. Fixed contact supports (3, 4) and a contact spring connection pin (5) which consist of semi-finished wire with a preferably rectangular or square cross-section are embedded in a flange (12) of the coil body (1). The inventive electromagnetic relay is therefore very simple to produce. There is no wasted material, no punching tools are needed for the contact connection parts and since no particles of plastic are abraded by insertion, there is no risk of this impairing the quality of the relay.

A mechanical switching device (1) comprising a base member (3), at least one pair of elongated conductor members (5) mounted on the base member, each conductor member comprising a conductor end (7), wherein the conductor ends of the pair of conductor members are separated by a gap (9), a middle member (11) mounted on the base member, a switch member (13) adapted to establish and disestablish an electrical connection between the conductor ends of the pair of conductor members. Each of the conductor members comprises an opening (50) in which a respective protruding part (52) is received. The protruding parts are provided on and extend from the middle member so that the conductor members are electrically isolated and protected from the surrounding environment around the device.

Abstract:
The invention relates to a relay formed by a magnet system (1) which contains a wound coil body (2), an L-shaped core disposed axially therein and an L-shaped armature (4), in addition to a base (6) made of insulating material. Connecting elements (63, 64) protrude from the bottom side of said base, on which fixed (62) and moveable contact elements (61) are arranged. The moveable contact elements (61) are actuated by means of a sliding element (8) coupled to the armature. Fixing prolongations (34) are provided on the magnet system to fix the magnet system (1) to the base (6). Said prolongations engage in elongations (61) of the base (6) that are formed upwards and which firmly connect the magnet system (1) and the base (6). The open end of the transversal limb of the armature (4) is placed on the open end of the longitudinal limb of the core (3). The armature (4) is fixed by means of a U-shaped spring(5) surrounding the armature. Said spring is fixed to the longitudinal limb (41) of the armature by one of its arms. The second arm is inserted in a recess located between the coil body (2) and the core (3).
