  • Universal matrix switching device
    Patent number: 4692578
    Abstract: A universal matrix switching device used with an automatic test system under computer control for interfacing with a unit under test. The switching device providing high speed switching of conductor pins in a matrix board. The device using oppositely disposed push-type actuators to move the conductor pins from a first conductor position to a second conductor position and returning the pins to the first conductor position.

  • Universal matrix switching device
    Patent number: 4618755
    Abstract: A universal matrix switching device is used with an automatic test system under computer control for interfacing with a unit under test to test system instrumentation. The switch has impedance matching with isolation between signal paths for high frequency transmission quality. The device uses movable switch actuators serving as multiple cross-point switches embedded in a matrix board with conductors.
