Abstract
A power window switch includes an operating knob having a knob-leg with a bifurcation formed therein, the operating knob being supported so that the operating knob can be operated to rock, and an auto switch supported in a housing and having an operating boss that engages the bifurcation formed in the knob-leg. When the operating knob is operated to rock, the operating boss receives a force from the bifurcation to operate the auto switch. The slide switch has walls that face an end of the operating boss projecting in a direction perpendicular to a plane in which the knob-leg swings. The walls are spaced apart from the end of the operating boss by a distance d shorter than a width D of the knob-leg. This arrangement minimizes the possibility of the knob-leg disengaging from the operating boss without increasing the thickness of the knob-leg.
