A switch for a two-conductor transmission line 5, 6 comprises a stub line 2 having sections 7 to 12 of two-conductor line having different characteristic impedances, and means to vary the capacity termination of the stub line. The length of each section is preferably an integral odd number of quarter wavelengths. The impedance of the sections may vary alternately and the variation may be obtained by varying the dielectric between the conductors, e.g. air and polythene. The inner conductor of the section 7 may be thickened to improve the attenuation/frequency characteristic of the switch when closed. The capacity termination of the line 2 may be varied by an electromagnetic device 15 which when the direction of flow of the energizing current is changed moves a rod 14 fixed to a rod 13 by a length of dielectric material. The movement of the rod 13 is limited by adjustable stops 23, 24. The device 15 may be mechanically biased to prevent the necessity of keeping it continually energized. In a modification, the capacity termination may be varied by a vane which rotates in the plane of the stub line axis and passes through slots in the conductors 3, 4. An adjustable screw may project through the conductor 3 near the end of the line 2 to preset one of the limiting values of the capacity termination. The switch may include a second identical stub line spaced #/4 from the first. Each stub line may have another stub line connected in parallel across the line 5, 6, these additional stub lines serving to compensate for any reactive impedance presented by the switched stub line. Specifications 659,812 and 696,394 are referred to.
