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.

A universal matrix switching device connected to an electronic controller for matrix switching two sets of electric signal pairs, the device comprising:
- a position table with plate having a plurality of actuators mounted thereon, the actuators under electronic control;
- a matrix board having a plurality of apertures therethrough and slots cut on both sides of the board and orthogonally oriented with the slots forming a grid pattern, the slots and apertures slightly overlapping;
- transmission conductor strips received in the slots for conducting a signal input to output;
- and
- a plurality of movable pins received in the apertures in the matrix board and having electrical contacts therearound, one end of the pins extending outwardly from the matrix board for engagement with the actuators, the actuators when actuated engaging the pins for moving the pins in the matrix board and providing contact between the transmission conductor strips in the slots on both sides of the matrix board.
A universal matrix switching device connected to an electronic controller for matrix switching two sets of electric signal pairs, the device comprising:
- a position table with plate, the plate having a plurality of bi-directional solenoids mounted thereon, the solenoids having latches extending outwardly therefrom, the solenoids under electronics control;
- a matrix board made up of a main board and status board disposed adjacent each other, each of the boards having a plurality of apertures therethrough and indexed with each other and slots cut on both sides of each board and orthogonally oriented with the slots forming a grid pattern, the slots and apertures slightly over-lapping;
- transmission conductor strips received in the slots for conducting a signal input to output;
- and
- a plurality of movable pins received in the apertures in the main board and status board of the matrix board, the pins having electrical contacts therearound, one end of the pins extending outwardly from the matrix board toward the latches of the bi-directional solenoids, when actuated the latches engaging the ends of the pins for moving the pins in the matrix board and providing contact between the transmission strips in the slots on both sides of the boards.
A universal matrix switching device connected to an electronic controller for matrix switching two sets of electric signal pairs, the device comprising:
- a position table with plate, the plate having a plurality of bi-directional solenoids mounted thereon, the solenoids having latches extending outwardly therefrom with the end of the latches "T" shaped, the solenoids under electronic control;
- a matrix board made up of a main board and a status board disposed adjacent each other, each of the boards having a plurality of apertures therethrough and indexed with each other and slots cut on both sides of each board and orthogonally oriented with the slots forming a grid pattern, the slots and apertures slightly overlapping;
- transmission conductor strips received in the slots for conducting a signal input to output;
- and
- a plurality of movable pins received in the apertures in the main board and status board of the matrix board, the pins having electrical contacts therearound, one end of the pins extending outwardly from the matrix board toward the latches of the bi-directional solenoids, the "C" shaped ends of the contact pins with the "T" shaped latches engaging the "C" shaped contact pins ends for moving the pins in the matrix board and providing contact between the transmission strips in the slots on both sides of the main board and status board.
