Abstract
A press button device includes a button unit having a main body with a surrounding wall, and an actuating member protruding from an inner side of the main body for actuating a control switch. A flexible connection unit includes a button-coupling portion connected to the surrounding wall in an airtight manner, a fixed portion radially spaced apart from and surrounding the button-coupling portion, and a deformable portion interconnecting the button-coupling and fixed portions. The deformable portion is elastically displaced relative to the fixed portion when the button unit is pressed, and restores the button unit to its original position when the pressing force thereon is removed.
