    Abstract: A system for isolating a fault in a direct current (DC) grid using thermionic arc extinction. The system includes a DC grid that includes a transmission line. The DC grid also includes a plurality of current interrupters disposed on the transmission line. Each of the plurality of current interrupters on the transmission line are electrically coupled to one another in series. At least one of the current interrupters includes a fixed terminal end and a moveable terminal end. Further, at least one of the current interrupters has an arc shield housing at least two arcing contacts. At least one of the arcing contacts comprises a first conducting material that has a first vaporizing point.

    Abstract: A switch assembly includes a plurality of electrical devices and a plurality of user activated switches. The plurality of electrical devices each include a control terminal. Each of the electrical devices causes a different distinguishable output to be provided when a control signal is asserted on the control terminal of one of the plurality of electrical devices. The plurality of user activated switches include carbon-coated contacts. Each of the user activated switches when asserted provides the control signal to the control terminal of one of the plurality of electrical devices.

    Abstract: A keyboard for a musical instrument having a plurality of elongated keys with each key having a rearwardly extending actuating arm. The arm has an upper and a lower nonresilient switch actuator for actuating a respective first and second keyboard switch with each switch having a substrate with at least one fixed contact. A deformable membrane has coupled thereto a movable contact which is adapted for movement into and out of electrical connection with the fixed contact. The first and second switches are positioned so that the lower actuator normally maintains closed the first switch and when the key is actuated the first switch opens and the upper actuator closes the second switch. The deformable membrane is formed of Poron cellular urethane which distributes and absorbs the actuation force and springs back to its undeformed shape when not actuated.
