Abstract

This system actuates reed relays according to a two-coordinate selection. A matrix crosspoint comprises two reed relays R 1 and R 2, line wire L and column wire C. The actuating system is composed of permanent magnet M sandwiched between two soft magnetic tubes T1 and T 2 into which wires L and C are, respectively, threaded. Any of these tubes becomes saturated when its wire carries current.

Reed Relay Matrix Crosspoint

This system actuates reed relays according to a two-coordinate selection. A matrix crosspoint comprises two reed relays R 1 and R 2, line wire L and column wire C. The actuating system is composed of permanent magnet M sandwiched between two soft magnetic tubes T1 and T 2 into which wires L and C are, respectively, threaded. Any of these tubes becomes saturated when its wire carries current.

If one wire only is live, one of the tubes T1 and T2 is not saturated. Flux from M is free to spread out and close reed switches R1 and R2. This enables a two- coordinate selection independent of the reed switch characteristics.

Another arrangement is the combination of such element with a coil around the whole assembly. This would provide holding current.
