A switch device has a case, an operation knob disposed above the case, and a connector disposed under the case. The connector has connection terminals and a housing supporting the connection terminals, the housing being formed with an opening portion from which the connection terminals are led out. The case is provided with an impervious wall extending downward from the case so as to be opposed to both side surfaces of the housing parallel to a leading-out direction of the connection terminals. The impervious wall is arranged across a gap from each of the both side surfaces of the housing.

Multi-level modulation that is hardly affected by non-linear characteristics of a power amplifier and is equal to or above 64-valued quadrature amplitude modulation (64-QAM) is provided.N (integer equal to or above 3) quadri-phase shift keying (QPSK) outputs having different amplitude levels, i.e., r2=r1·2−(i−1), i=2 . . . N with respect to a maximum amplitude level r1 are superposed after power amplification to form M(=22N)−valued/quadrature amplitude modulation (QAM), and N-1 outputs si except the quadri-phase shift keying QPSK-1 having the maximum amplitude r1 are subjected to power amplification in this formation, then the outputs are combined by a directional coupler to obtain a combined signal, and an output of the quadri-phase shift keying QPSK-1 and the combined signal are transmitted from two systems of antennas to be vectorially superposed and combined in a space. A series/parallel converter is provided before each QPSK unit to divide and input input data of 2N bits, and a variable gain unit and a variable phase shifter adjust a gain and a phase.

A switch includes: a case including a bottom portion and a side wall; a fixed terminal provided on the bottom portion of the case; a supporting member provided in the case; a movable contact strip supported by the supporting member so as to be pivotable in a vertical direction above the fixed terminal; a resilient member provided between the side wall of the case and the movable contact strip, and configured to urge one end portion of the movable contact strip obliquely upward; and a pressing member provided above the resilient member. The movable contact strip pivots and an opened-closed state between the movable contact strip and the fixed terminal is switched by pressing a center portion of the resilient member downward by the pressing member.

A mounting structure is provided which includes: a holding member provided on a mounting surface on a side of a vehicle body; and a held member provided on a casing, at least partially configured of an elastic body, and configured to be held by the holding member. The held member is mounted in a state of pressing the elastic member due to elastic force (indicated by a dotted arrow) of the elastic body.
