ABSTRACT:
The handset of electrosurgery or welding apparatus has two spaced contacts which make connection with the shaft of an electrode that is insertable into the handset. A low power alternating signal generator is connected to the forward contact. When the electrode is fully inserted into the handset and contacts the rear contact, the alternating signal is supplied to a detector. The detector is connected to a power generator and rams it on when the alternating signal is detected so that electrosurgery power is supplied to the forward contact.
