crossbar switch

An earlier telephone switch. First used in the late 1930s, it was a mechanical device that used magnets and metal bars (crossbars) to close connections. Crossbar switches have been replaced with electronic switches (large-scale, specialized computer systems). See ESS and DMS. See also physical layer switch.
