摘要： A make-before-break bypass switch is combined with a pair of probes projecting from a support where a member is provided with sockets to slidably receive the probes. The probes define a gap in a first RF circuit. The corresponding sockets are connected by a second RF circuit. A pair of spring clips on the support are connected by a bypass circuit on the support and are designed on retraction of the sockets from the probes to connect a bypass circuit between the probes before the sockets are completely disconnected from the probes. On application of the sockets, the sockets are designed to connect to the probes before a part of the member disconnects the spring clips from the probe. If the first RF circuit may carry signals in either direction and the second RF circuit is directional, the probes and sockets may be arranged to allow reversal of the sockets relative to the probes.

摘要： A conducting housing (to be closed by a lid) for a coaxial cable distribution network has a common port and one of an aerial or pedestal port. A motherboard carries an RF circuit and a transfer switch. In one setting of the transfer switch the RF circuit connects a coaxial pin at the common port with a coaxial pin at the pedestal port. In the other setting the common port pin is connected to the aerial port pin. When the aerial port is used on a rectangular housing, a transmission line forms part of the RF circuit between the motherboard and the aerial port. The transmission is preferably a central conductor spaced over most of its length by air from an outer conductor in the form of an inverted U enclosing the central conductor on three sides. Preferably a ground plane on the back of the motherboard connects to the transmission line outer conductor to provide a path entry in the housing at both ends for ground currents generated by signals in the RF path.
