An iontophoretic drug delivery system (10) having a flexible planar patch (12) including a medicament containing surface (26), and a controller (14) having circuits which supply electric current to effect drug delivery. The patch (12) is detachably coupled to the controller (14) and includes a plurality of spaced-apart electrical contacts. The controller includes an elastomeric connector which is made of alternating sections of electrically conductive and electrically non-conductive material which, during transcutaneous drug delivery, electrically coupled patch to the controller. The connection is maintained free of contaminants which could adversely affect the electrical connection by employing an abrasive wiping surface (60) to clean the electrical interconnection.
