1. A sealed electronic module comprising at least one actionable part, the module including a case comprising:
a watertight compartment containing a printed circuit board, said compartment being formed by a housing with only one opening, the housing containing the printed circuit board, and
a sealing element comprising a flexible element that is fixed directly to the housing and the printed circuit board, and is entirely covering the opening,
wherein the housing comprises an enclosure delimited by a bottom and a peripheral inner wall, wherein a surface opposite to the bottom is delimited by the opening,
wherein the housing includes ribbings extending on a surface of the peripheral inner wall from the bottom toward the opening, an extension of the ribbings being configured to arrange in the enclosure a peripheral part of a backside face of the printed circuit board in a same plane as a part of a surface of an edge of the opening, and
wherein the at least one actionable part is formed by a metal dome switch arranged in the printed circuit board and a part of the sealing element covering the metal dome switch, the metal dome being arranged with a convex side facing the sealing element.
