停波する欠点がある。However, in the above-described conventional four-terminal switch, when the rotary conductor is rotated and switched while the transmitter is energized, each coaxial terminal is opened or short-circuited. A reflected signal is generated. Therefore, when using such a coaxial switch to switch a high-power transmitter of the working backup system, the output of the transmitter is stopped for a short time. For this reason, there is a disadvantage that the wave is stopped until the switching operation is completed.

A four-terminal switch comprising one outer conductor including a pair of inner conductors, wherein a coupling plate is provided at each of both ends of the pair of inner conductors and at each of the inner conductors of the two pairs of coaxial terminals;
The pair of inner conductors are electromagnetically coupled, and the pair of parallel inner conductors are
The area of each of the coupling plates is set to be equal to the area of the two pairs of coaxial terminals.
By increasing the area of the coupling plate, the pair
When the parallel inner conductor rotates, it is parallel to a pair of coaxial terminals
One of the inner conductors is capacitively coupled to the other pair of coaxial terminals.
The other of the parallel inner conductors is not capacitively coupled.
4-terminal switch.
