The suction tube is electrically conductive and electrically connected to the contact wire and portions of both the contact wire and the suction tube, with its insulating layer, have a layer of plastic material molded thereabout to form a first insert. The first insert includes a body section having a surface through which a vent extends and an airway is formed within the first insert in spaced parallel relation with the upper surface of the first insert and in communication with the vent. A vent activation button is integrally formed from the upper surface of the body section and a longitudinally extending baffle forms the lower wall of the airway.
