The invention relates to an electrical switch and especially one with multiple positions for connecting multiple high frequency coaxial lines among themselves.

One of the objects of the invention is a coaxial switch with several positions of such electrical and mechanical construction that it is both proportionate high frequency ranges without large "losses as well as a relatively low ratio" of the voltage amplitudes can be operated, and also switch from one line to the other practically immediately and as a remote control can serve without direct manual operation '.

Another object of the invention is a coaxial switch with multiple positions and the noted feature constructed so that each of multiple outputs have the same physical structure and identical electrical characteristics.

Another object of the invention is a coaxial switch with multiple positions, wherein the output transmission lines via identical resistors certain

The central cavity is located so that it can accommodate a central coaxial cable connection 14, and several identical cable connections 15 are on the circumference fastened in holes, as best shown in Figure 2. The connections 14 and 15 each contain a short section a coaxial transmission line of the same characteristic Impedance as the cables the switch is designed for and the outer conductive sleeves of each Connection devices are firmly fitted, soldered or otherwise well fixed in the corresponding holes.

The central cavity 12 is closed by the generally cylindrical metal plug 19 which is soldered or otherwise attached to the recess 18. The plug 19 has a plurality of internal vertical cavities 26 which can be drilled inwards from their lower end, as shown, and which are oriented around the circumference at the same angle as the connections 1'5, so that the vertical axis of each cavity 26 is located directly above and in alignment with one of the contact buttons 24 on the straps 23. The lower ends of each cavity 26 are countersunk to receive an insulator with an end contact 29 secured centrally within it. The cavities serve as a housing for identical electrical resistors 31 * of which the lower terminal is electrically connected to an end contact 29, and the upper terminal of which runs through an opening 32 and with the metallic plug 19 or in another. Way is connected. Each Sehaltband 23 is arranged so that it normally exerts a significant gate tension between the button contacts en 24 and -the corresponding end contacts 29. The strips are flexible and can easily be bent down enough to interrupt the electrical connection 24, 29 and to establish electrical contact between the contacts 24 and the central contact disk 22 more Relaiswieklungen executed, designated generally by the Bezugsaeichen 33, wherein each relay includes an L-shaped magnetic Eahmen 34- (Jigur 2) adjacent to the upper Tordei - side of the body but secured 1o> is through a spacer 35 ^{held at a} distance and held in place by fastening screws 36 arranged in pairs' (FIG. 1).

The lower arm parts 39 of each anchor are provided with downwardly extending insulating pins 44, which are set up so that they extend through suitable incisions 45 in the spacers 35 (Figure 1), so that when the windings of a relay magnet are excited, the inward movement of the armature part 38 is a results in downward pressure exerted by the pins 44 on the respective belt links 23 to to interrupt the connection between the contacts 24 and 29 and a connection between the selected contact 24 and the middle contact disk 22 to produce »

It is intended that the switch according to the invention by an appropriate circuit for exciting certain Relaisniagnete to be able to control it remotely. This construction makes a connection of a peripheral connector possible with the center connection, while the other channels remain grounded via resistor 3I. A connection) of two, three or even all cable connections at the same time can also be carried out, if there is should be desired. A simple circuit for this is shown in Figure 3, in which a single controller Magnet windings 33 passed through switch 46

From the foregoing it can be seen that the invention results in a unique and improved coaxial switch which, while comparatively simple in

Structure and way of working is, however, a great variety when connecting multiple transmission lines for medium wave results. Each channel through the switch is structured so that it has the same mechanical structure and the same identical electrical characteristics for each non- ' used line has, which by a '.iiderstand is closed by a given '7ert. Die, parts of the switch unit are arranged and constructed in such a way that they provide simple and reliable remote control with a minimum attenuation and crosstalk, and with VSWE characteristics, which are considerably better than those which one generally encounters in devices of this kind.,

Modifications to the example described, such as the direct earthing of the unused channels or the omission of the terminal contact circuits for unused lines, are possible. borrowed without exceeding the scope of the invention »■" ζ "■■■ · ■ '."
