SWITCH DEVICE

PROBLEM TO BE SOLVED: To provide a switch device capable of surely executing a switching operation even in submersion under water, and of extending a service life, and manufacturable at a low cost. SOLUTION: When an operation knob 12 is operated to the window lowering side, a pressing projection 13c of a drive member 13 presses an operation plate 15, a down-side contact block 16b is pressed, and contacts 16h of second elastic-contact legs 16f of the contact block 16b come into contact with fixed contacts 17b of a wiring board 17. Thereby a power voltage Vcc is supplied to a CPU 21 through the fixed contact 17b on the down-side. A window lowering drive signal is transmitted to a drive circuit 25 from the CPU 21, the power voltage is applied to a motor 26 by the drive circuit 25 and the motor 26 is rotated in a first direction. By the rotation of the motor 26 in the first direction, the window is lowered and operated to be opened. COPYRIGHT: (C)2007,JPO&INPIT
