  • Patent number: 11495423
    Abstract: The resin molded article is molded by using an electrode sheet as an insert in a state where one surface of the electrode sheet is closely attached to an inner surface which serves as the inner side of the operation surface. The electrode sheet is formed by using, as a base material, a thermoplastic synthetic resin sheet which outputs an electrical signal according to the amount of change of electrostatic capacitance generated by a contact operation with respect to the operation surface. At least a whole or a part of the inner surface is formed in a three-dimensionally curved surface, and a passage is formed in the electrode sheet so as to allow a molten resin following in through a gate formed in a die which comes into contact with the other surface of the electrode sheet during molding to pass toward one surface side of the electrode sheet.

  • Patent number: 11476064
    Abstract: A rotor system for a multi-pole rotary electrical switch having a rotor with a top and a bottom. Bus plate connectors are held in chambers on the bottom of the rotor. Retainers in the chambers, engaging only sides of the bus plate connectors, prevent the bus plate connectors from dropping out of the chambers when the bus plate connectors are placed above bus plates in a bus plate holder to place the switch in an “OFF” position. Support members extend from a side of the rotor to support the bus plate connectors above the bus plates. When the rotor is rotated to the “OFF” position the support members are rotated up onto support posts positioned in the bus plate holder. When the rotor is rotated to an “ON” position the support members are rotated off the support posts and the bus plate connectors are pressed down against the bus plates by a spring, thereby creating electrical connections between the bus plate connectors and the bus plates.
