By fire, the task is to create a switching relay * which enables a reciprocal connection between a coaxial line on the one hand and a second or third coaxial line on the other hand to be established within a short switching time, e.g. within two milliseconds. Basically, it should be expensive / inexpensive from afar, moreover, the access parts should be designed to be as free from reflections as possible, so that even at high frequencies, for example at around 500BiHz, a low degree of flexibility is guaranteed. The operational reliability of the relay should be very high -.- even without maintenance. The construction is intended to enable a compact binary structure, built up in coaxial configuration, in which the contacts are completely shielded by the external conductor a transmitter or a receiver required - - - - ^{.. ■:} -;.?.,. ■

Leaf spring connected to a fixed piece of inner conductor - and can thus move in relation to inner conductors II and II *. If you now send a direct current through coil III, a magnetic field builds up, supported by the soft iron bracket IV, under the influence of which the inner conductor I polarizes, while one of the permanent magnetic fluxes is strengthened, the other is weakened on the other hand = depending on the direction of the coil current, the inner conductor I is placed against the conductor II or ΙΓ ¹ . The desired connection can thus be established by appropriately controlling the coil current »The precise contact spacing can be set _{in a simple manner 2, B 0} by pressing the movable thin-walled inner conductor Γ in an oval shape» After switching over, the control current can be switched off, or ' but it serves as a farmer's current to • increase the contact pressure »This relay can also be used in pulse mode.

When the direction of the current is reversed in the windings 12- and 12 *, the strengthening and weakening of the flux are interchanged, the core 5 slides in the rest position _; R ¹ . The stroke flow is shown in dashed lines in FIG. An essential feature of the compact belais structure is that the core 5 in its function as an anchor, conductor and contact "carrier, with the continuous and reversal flow (compare FIG. 5) , or with the constant flow and reversal flow (compare FIG. 6) and The contact arrangements used in the exemplary embodiments of FIGS. 2 to 4 can be used for direct current as well as for low-frequency or high-frequency currents.
