摘要： A first set of conductors (e.g. 25 of them) leading for example to a communications modem, is connected by way of a corresponding set of normally-closed switches to corresponding conductors of a second set, leading for example to local equipment such as a computer. At least one of the above sets of conductors is also connected to connector means into which a multi-wire (e.g. 24 wire) patching cable may be plugged. The plugging-in of the patching cable automatically opens the normally-closed switches to isolate the first and second sets of conductors from each other, as is usually desired for patching purposes. Preferably the switches are magnetically-operable reed switches, switched between their open and closed states by magnet means controlled by the plugging-in of the patching cable. Preferably the plugging-in moves the magnet means physically from a position near the switches for which the switches are operated to one of their states, to a position more remote from the switches for which the switches assume their opposite state. In a preferred embodiment the magnet means are mounted on a slidable panel, which is moved slidably by a protruding tab on the patching-cable plug when the plug is inserted, and the panel is returned to its original position by a spring when the plug is removed. Patching of many-conductor cables is thereby made possible with a simple single motion by the operator, and with reliable and relatively inexpensive apparatus.

摘要： An array of magnetically-actuatable electrical switches is controlledly operated in response to changes in position of a movable member controlling the magnetic field reaching the switching elements. The movable member may for example comprise a panel, supporting permanent magnets which are moved into switch-closing or switch-opening positions by motion of the panel, or a movable magnetic shielding arrangement used in conjunction with fixed permanent magnets so that the position of the magnetic shield determines whether the switches are open or closed. The preferred arrangement is such that the motion of the movable switch-controlling member can be accomplished mechanically by a manually-operable actuator or electrically by an electrically-controlled solenoid arrangement, at the option of the operator. In one preferred embodiment a latching arrangement is provided which holds the movable switch-controlling member in one of two stable positions until either the manually-operable mechanical actuator or the electrically-controlled solenoid is momentarily operated to move the movable member to its opposite stable position. In other cases, the switch-controlling movable member may, in effect, latch itself in that it maintains whatever position it is placed in, due to its own inertia and associated friction, until it is forced into an alternate position. In still other embodiments the movable switch-controlling member may be spring-biased to one of its two operative positions, so that it is held in its alternate operative position only while displacing force due to the mechanical actuator or the solenoid device continues to be applied thereto. The apparatus not only makes possible the desired electrical control of switching, either from a local position or from a more remote position such as a central control site, but also enables local mechanical control of switching in the event that power outage or other malfunction prevents the electrical control from functioning properly, or for other reasons.
