PURPOSE: To handle the four operational modes of a power window, to improve assembling work and maintenance by decreasing manhours, and to reduce costs by making a substantial constituent part into a module structure. CONSTITUTION: A pair of movable contact pieces 25D, 25U are turned on and off by a pair of pressing bodies 20 to be moved by the small rotation in the first direction of a key top 1 and in the second direction opposite to it, and the manual mode for raising and lowering a power window is operated. Any one of a pair, of cams 30D, 30U is pressed down by any one of a pair of cam pressing protrusions 12D, 12U to be rotated by the large rotation in the first direction of the key top 1 and in the direction opposite to the first direction, and a fixed switch terminal corresponding to the pressed cam, out of a pair of fixed switch terminals 35D, 35U is turned on and off. Therefore, the automatic mode for raising and lowering the power window is operated and copes with the four operational modes of the power window, and assembling work and exchanging of parts can be easily performed by making a module structure. |
