PROBLEM TO BE SOLVED: To provide an antenna connection changeover device by which a high-frequency signal flowing between an antenna and a feeder circuit is less likely to be attenuated, and a solder connector with a printed wiring board is less likely to be damaged.SOLUTION: A common terminal, a normal close terminal, and an antenna connection terminal are arranged so that their projection shapes onto a mounting surface of a printed wiring board are appeared continuously on the same straight line. A leg part of the antenna connection terminal is connected by solder to a land pattern of the printed wiring board, at a position on the straight line separated from a leg part of the common terminal connected by solder to a power feeding pattern. Since unnecessary inductance is not generated in a transmission path from an antenna to the power feeding pattern, a high-frequency signal is not attenuated. Since solder connection to the pattern on the printed wiring board is possible at two positions separated from each other on the straight line, a solder connector is less likely to be damaged even if a moment of rotation including the direction is generated. |
