Electronic switch and communication device including such a switch
First Claim
1. A switch comprising:
- a terminal of a first type and at least two terminals of a second type, and a number of circuits capable of ensuring exclusive connection of one of the terminals of the second type to the terminal of the first type as a function of a set of control signals whereinthe terminal of the first type is connected to a common point by a first circuit;
each terminal of the second type is connected to said common point by a second circuit, with each second circuit comprisinga portion that is magnetically coupled to said first circuit, anda static switch mounted in parallel with said portion and capable of being controlled in an off state in order to connect the terminal of the first type to the terminal of the second type associated with the second circuit in question.

Abstract
Switch including a terminal of a first type and at least two terminals of a second type, and a number of circuits capable of ensuring exclusive connection of one of the terminals of the second type to the terminal of the first type as a function of a set of control orders wherein the terminal of the first type is connected to a common point by a first circuit; each terminal of the second type is connected to the common point by a second circuit, with each second circuit including a portion that is magnetically coupled to the first circuit, a static switch mounted in parallel with the portion and capable of being controlled in the “off” state in order to connect the terminal of the first type to the terminal of the second type associated with the second circuit in question.
