Abstract: A simple and reliable electrosurgical instrument includes a cable having a main contact wire and first second insulated switch wires all provided with a short insulated or bare portion. The cable is received in a main member having a first holding mechanism for holding the switch wires adjacent uninsulated portions thereof on one lateral side and spaced from one another as well as a second holding mechanism for holding the switch wires adjacent the uninsulated portions thereof on the other lateral side so that the uninsulated portions span between the first and second holding mechanisms and are spaced longitudinally from one another. A blade receiver receives an electrode blade and is then electrically connected to the contact wire. A switch device selectively connects one of the uninsulated portions of the switch wires to the contact wire during operation. The first and second holding mechanisms preferably include channels and a cover includes projections which hold the wires in place.
