Abstract

A method for manufacturing a handle for an electrically operated personal care implement comprises the following steps: providing a metal tube housing having a metal wall with an opening therein and an inner surface defining an inner cavity for accommodating an energy source; providing a hard switch component comprising a frame with a recess; attaching the frame of the hard switch component to the inner surface of the metal wall, the frame surrounding the opening and providing an undercut between the recess and the inner surface, the undercut being open towards the opening; and at least partially over-molding the opening to form a soft switch component in the undercut, thereby forming with the hard switch component a switch assembly for activating the energy source, the switch assembly sealing the opening from the inner surface of the metal wall.
