Abstract
An array of reed switches () is assembled on a circuit board () having a plurality of through-apertures () with one reed switch () disposed in each aperture with the axis of the switch envelope () extending perpendicularly to the plane of the board. A plurality of coils () is provided on the board so that each switch () is surrounded by a respective coil, the coils being connected to conductors on the board for operation of the switches. Also disposed is a control circuit wherein the reed switch drive coils () are connected in series across a constant-current voltage source and a respective solid-state switch TR, TR. . . connected across each coil, with divers for each solid-state switch to permit operation of a selected reed switch.
