  • Patent number: 6023212
    Abstract: An electromagnetic relay having a manual actuator wherein at an edge of the relay's housing is an opening formed in the shape of a mounting slot in which a pivot lever is mounted with a hinge segment. In an idle state, an outer lever segment of the pivot lever is lowered in a cavity of a housing wall while an inner lever arm extends along a housing wall perpendicular thereto. When the pivot lever is actuated, the inner lever arm actuates a movable relay part, in particular a bolt, up to a first operating position. When the pivot lever is rotated further, the inner lever arm can be locked with the movable relay part.

  • Patent number: 5907268
    Abstract: A relay is provided with fixed contact mounts anchored in a base, as well as contact springs arranged between the fixed contact mounts. The springs are actuated at their free ends. The contact springs each have spring mounts that include terminal segments anchored in the base, respectively parallel to the fixed contact mounts, but outside the space enclosed by them. These terminal segments are connected with the appertaining contact springs via U-shaped connection segments; the connection segments are guided in corresponding guide channels of the base in an insulated fashion. In this way, several sets of switchover contacts can be arranged in simple and space-saving fashion in a relay base, given a predetermined terminal configuration.

  • Patent number: 5894254
    Abstract: A relay is formed by a magnet system containing a wound coil body, an L-shaped core arranged axially therein, an L-shaped armature and a base element with terminal elements. Stationary and moving contact elements are arranged between the base element and the magnet system. The armature is mounted with the free end of its transverse leg at the free end of the longitudinal leg of the core. The armature is secured through a U-shaped armature spring wrapping around the armature. The spring is secured with one arm at the longitudinal leg of the armature and a second arm is inserted in a recess between the coil body and the core. The actuation of the moving contact elements is provided via a slide coupled to the armature. This slide is hooked to the armature by spring tabs of the armature spring at opposing sides of the armature through snap latches formed at the ends of the side arms of the slide.

  • Patent number: 5864271
    Abstract: A magnet system has a U-shaped core yoke whose yoke leg and core leg form a magnetic flux circuit together with an armature. A constriction section with reduced cross-section is provided at a location of the magnetic flux circuit, preferably at the core leg; a ferromagnetic bridge element with a flat permanent magnet is coupled to the magnetic flux circuit parallel thereto. Since the constriction section enters into saturation when the armature is attracted, the armature is held fast opposite a restoring spring. As a result of the inventive arrangement, a geometry for a magnetic circuit arrangement that is fast and inexpensive to manufacture is provided.

  • Patent number: 5844456
    Abstract: An electromagnetic relay is provided with an electromagnet system with a U-shaped core yoke and an essentially flat armature, which form a working air gap on a longitudinal side underneath the coil winding. One yoke limb lies immediately on the coil winding, so that the make motion of the armature is towards the coil. In this way, a relatively large contact room is formed underneath the yoke limb and a movable contact spring extends approximately parallel under the armature. The contact spring is actuated by the armature which draws an actuating element. The relay enables a relay for high switching capacity with a changeover contact and with large insulating distances between the magnet system and the contact arrangement.

  • Patent number: 5801608
    Abstract: The relay has a magnet system with an armature that operates on a switching spring via an actuating element. This switching spring has a frame-shaped contact spring as well as a fork-shaped reset spring, intermeshed in one plane and mutually decoupled, whereby the reset spring guides the actuating element via at least two linkage points lying in a line parallel to the pivot axis. The relay of the present invention provides a compact construction with few individual parts and a very low-friction operation.

  • Patent number: 5651464
    Abstract: A package for receiving articles in successive arrangement and being of a type having one surface provided with projections, includes an outer enclosure defining an interior; and an insert receiving the articles and being placed in the outer enclosure. The insert has at least one inside surface which is provided with an elevation protruding inwardly from the inside surface into the interior of the enclosure, with the projections of the articles engaging in an area between an inner wall and the projection of the insert.
