  • Patent number: 9281598
    Abstract: A contact element for making electrical contact with a contact area of a mating contact element, wherein a contact region forms at least two contact points, and wherein the two contact points are distinguished from one another in the new state in respect of the distance from the contact area of the mating contact element, so that, in the new state, a first of the contact points makes contact with the contact area and, after a defined amount of wear of the first contact point, the second contact point makes contact with the contact area.

  • Patent number: 9112292
    Abstract: A terminal structure provided with a male terminal and a female terminal that includes with at least one set of elastic plate parts is disclosed. The male terminal is inserted between the elastic plate parts of the female terminal in a predetermined direction to cause each side surface of the male terminal to be pressed from each side of the elastic plate part due to the elastic force of the elastic plate parts, and the male terminal and the female terminal are electrically connected to each other. A position of the surface of the male terminal with which one elastic plate is brought into contact differs, in the insertion direction of the male terminal, from a position of the other surface of the male terminal with which the other elastic plate is brought into contact.

  • Patent number: 6323448
    Abstract: A stab assembly (41) in which a spring clip (24) and a conductor member (16) define a pair of engagement surfaces for engaging a stab blade (12). The conductor member (16) has an opening (34) to allow for the insertion of an extended surface of the spring clip (24). Once in position, the spring clip (24) and conductor member (16) are frictionally engaged and define a channel (126) that will accept and hold a stab blade (12). The stab assembly (14) is retained within a molded case circuit breaker (10) and provides electrical contact between a bus bar and the circuit breaker.

  • Patent number: 5635750
    Abstract: A micromechanical electrostatic relay has a base substrate with a base electrode and a base contact piece. The relay also has an armature substrate with an armature spring tongue that curves away from the base substrate, and an armature electrode and an armature contact piece. When a control voltage is applied between the two electrodes, the spring tongue unrolls on the base substrate and thus closes the contact. The curvature of the spring tongue in the quiescent condition is produced by a coating with a compressive strain layer. In order to avoid undesired transverse arcs of the spring tongue, the compressive strain layer is subdivided into strips by slots in a longitudinal direction of the spring tongue. A tensile stress layer applied in surface-wide fashion over the strips and slots reinforces the compensation effect.

  • Patent number: 4778964
    Abstract: A subminiature switch includes a housing having a base portion in the central part of which is implanted a common stationary contact comprising a rod-shaped conductor and having a common stationary terminal extending outside the housing. Implanted in the base portion on both sides of the common stationary contact are switching stationary contacts each comprising a rod-shaped conductor bent at two locations and having a switching stationary terminal extending outside the housing. The arrangement is such that the inter-terminal spacing outside the housing is greater than the inter-contact spacing inside the housing, thus making it possible to reduce the size of the switch housing and adapt the switch to various mounting structures.

    Abstract: A miniature switch has an actuator block operated by a toggle lever and formed to include a recess in one side face thereof, the recess being open at its bottom and on one side and having a retaining portion. The upper part of a movable contactor is provided with an engagement portion loosely fitted into the retaining portion of the actuator block to mount the contactor in the actuator block. The arrangement is such that when the actuator block is covered by a switch housing, the inner wall surface of the housing is situated at the side of the movable contactor to prevent the movable contactor from becoming detached from the actuator block.

  • Patent number: 4675486
    Abstract: A compact pushbutton switch comprises a housing in which three chambers are formed and connected by a common contact member. A fixed contact, a nonconducting member forming a continuation to the fixed contact, a slider movable along both the fixed contact and the nonconducting member, a movable contact fixed to the slider, a control pushbutton mounted to the slider, and a coiled spring are mounted in each of the chambers. The spring is made of an electrically conductive material, and interposed between the common contact member and the movable contact to bias the movable contact out of contact with the fixed contact. When no control pushbuttons are depressed, each spring acts to hold the movable contact out of electrical connection with the fixed contact. When any one of the pushbuttons is depressed, the corresponding spring serves to establish an electrical connection between the corresponding movable contact and fixed contact by its electrical conductive property.

  • Patent number: 4590343
    Abstract: A contact arrangement for an isolating switch used as a ground connection of a switch system includes two switch pieces which are movable relative to one another, one of which is a knife and the other is a gripper. The gripper includes two contact pieces which are located opposite and parallel to one another and which engage the knife in the cutting-in state. Each contact piece is in turn formed by a plurality of adjacent contact elements. Such a contact arrangement is simple and economical to produce, while providing reliable contact-making for both high and low currents in spite of only slight static contact pressure. This result is achieved because the contact elements are U-shaped contact lamellae. Each lamella includes first and second legs connected via a curved part, the first leg being supported on the knife in the cutting-in state and the second leg being supported on current terminals formed on the contact pieces.

  • Patent number: 4486636
    Abstract: A break contact arrangement is disclosed. One piece spacers provided with angled-off arms determine the mutual spacing of contact segments and guide the contact segments within a holder comprising side walls and sheet metal covers. The contact segments are spaced by the arms of the spacers. Each spacer includes a U-shaped central portion which is received in a recess of the contact segments and extensions at opposite ends which are fastened to the side walls of the holder. The contact forces are supplied by one-piece springs which have spring arms for each contact segment. The break contact arrangement is particularly well suited for pullout-type low-voltage and medium-voltage switchgear for connecting conductors of rectangular cross section.
