ABSTRACT:
In a method for producing a reed relay, and a reed relay produced in accordance therewith, for switching r.f. currents at high voltages, it is proposed to arrange the coil, which is wound upon a normal bobbin with flanges on both sides, within a low-ohmic coil shielding by mounting the bobbin with the coil in an outer tube of brass, fitting an inner tube, likewise of brass, in the bobbin and connecting the two tubes by annular end disks placed on the two ends and joined with the tubes by pressing. The whole assembly comprising the bobbin, the coil and the shielding is then mounted on a two-piece bobbin carrier, and the vacuum glass tube of the r.f. reed switch is inserted into the bearing tube of the bobbin carrier and preferable fixed therein by means of a silicone hose.
