    Abstract: Angled spring contacts and switches made with contactors containing angled spring contacts are disclosed. The housing for the angled spring contacts has a generally cylindrical shape. The contacts are contained within the housing with their ends extending from the housing on either side. The contacts are formed by making bullet-shaped internal contacts that are joined by a spring. The spring is mounted to the two contacts to urge the two contacts away from each other at an angle to a longitudinal axis of the housing. This angle forces contact between each contact and the housing in at least two places, thus creating redundant paths between the contacts. Switches, such as plunger switches having a normal or OFF position, and an actuated or ON position, may be made with one or more angled spring contacts. The contacts have separate surfaces for electrical conduction and for arcing.

    Abstract: Structure for forming a switchable shunt for a suspension assembly having conductive, insulating and metal base layers. The shunt includes a bridge in the conductive layer with either a continuous connection or small gap between ends of the bridge. The continuous connection of the bridge is severed either by temporarily moving the lands out of their original plane by stretching and rupturing the bridge or by shearing the continuous connection of the bridge. For the sheared or gapped bridge, at least one end of the bridge is moved out of the plane, compressed and elongated. When released, the separated ends of the bridge overlap and contact each other to form a normally-closed switch. To subsequently open the switchable shunt, at least one of the lands is moved out of plane to physically and electrically open the connection between the separated and overlapped ends of the bridge.

  • Patent number: 6445275
    Abstract: An overload-protection push-button switch with automatic resetting mechanism of pull-push type is disclosed. The switch is characterized in that a pull-push rod and a floating rocker are used to transmit a force on a pressing stem to a conducting leaf. Moreover, a guiding mechanism including a guider and a guided-member on the floating rocker is used to guide the moving direction of the floating rocker under the action of the pull-push rod. Thus, the direction force on the pressing stem can be different from the moving direction of the nose of the floating rocker by which the conducting leaf is actuated. Moreover, in case of overload, a positioning unit for positioning the pressing stem will be unlocked and thus the pressing stem can automatically return to its reset position. In view of the above, a push-button switch that has simple and easily-assembled structure as well as an operation of exactly tripping is available.

  • Patent number: 6350970
    Abstract: A switching mechanism is utilized in a heating appliance, such as a toaster, that includes a bread support that supports a food item to insert and remove the food item from a cooking cavity of the appliance. The appliance includes an electronic circuit that controls operation during a heating cycle. The switching mechanism includes a switch having a first terminal adapted to receive a power signal and a second terminal coupled to the electronic circuit. The switch operates responsive to an applied switching force to couple the first terminal to the second terminal and thereby apply power to the electronic circuit. A switch actuator has a first end, a second end, and a retaining member near the second end. The second end is attached to the appliance to rotate about an axis. The switch actuator operates responsive to a force being applied to the bread support to rotate about the axis to a first position and apply the switching force to the switch so power is applied to the electronic circuit.

  • Patent number: 6087603
    Abstract: The present invention concerns a switch, preferably a steering column switch for an automobile, with which both control currents and load currents are to be controlled. The object of the present invention is to mostly prevent soil and scale from forming on the contact surfaces. The present invention achieves this object by transforming the grinding movement of the operating element into a movement of the contact points perpendicular to one another with the help of a mechanical control. Advantageous embodiments involve the design and positioning of the contact points as well as the design of the mechanical control and a method of assembling the switch according to the present invention.

  • 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.
