Abstract
A sealed pushbutton for a wristwatch includes a pushbutton head that is movable between a resting position and an active position, a first fixed conductive element, a second movable conductive element, and an elastically deformable capsule. The elastically deformable capsule hermetically covers the first fixed conductor, and an upper surface of the capsule is in physical contact with a lower surface of the pushbutton head and the capsule is locatable in a non-deformed position when the pushbutton head is in its resting position and in a deformed position when the pushbutton head is in its active position. The first and second conductive elements form a capacitive or resistive switch device, and the switch is in open state when the pushbutton head is in its resting position and in closed state when the pushbutton head is in its active position.
