PROBLEM TO BE SOLVED: To select a plurality of radio wave receivers, by taking into consideration the strength of radio waves from a radio wave transmitter and the reception level. SOLUTION: In the switching system comprising at least two or more radio wave receivers and one or more radio wave transmitters, the system is provided with a radio wave strength measuring part capable of arranging the first to n-th radio wave receivers with equal intervals in between, arranging one or more radio transmitters at a position, where all the receivers from the first to n-th can receive waves, and allowing the first to the n-th radio wave receivers to measure the strength of one or more radio transmitters. The radio wave strength, transmitted from one or more radio transmitters, is measured by the radio wave strength measurement part of the first to the n-th radio wave receivers to decide which of the radio wave receivers is selected from among the first to the n-th according to the strength of the radio wave strength.
