Abstract
A matrix of three pole, high speed, low current relays for connecting test equipment to a device under test is provided with improved interconnect buses. The relays are mounted in rows and columns with their three pairs of leads extending vertically. An input interconnect bar having three conductors extends horizontally along each row of relays, each conductor being connected to a respective one of each pair of leads. A bottom interconnect bar having three buses extends perpendicular to the top interconnect bars along each column of relays, each bus being connected to a respective one of the leads. The ends of the leads are aligned at a 45.degree. angle with respect to the interconnects. The interconnect bars are enclosed in shielding guard tubes and are removable to permit replacement of the relays.
