SWITCH DEVICE

A switch device includes a panel housing a knob, the panel having a wall face around the knob. In at least one of outside faces of the knob, the outside faces opposing the wall face and another member adjacent to the knob, the outside face has a base part formed on an upper side thereof and a recess part formed in a lower side thereof. The recess part extends to a lower end of the outside face. The base part has an obliquely downwardly inclined parts formed on a lower edge part thereof. Accordingly, the device can ensure stable operation of the knob by discharging, from a gap between the panel and the knob, liquid that has entered the gap.
