Abstract
An electrosurgical generating system and method including an electrosurgical generator; and a handpiece including an active electrode connected to the electrosurgical generator for applying electrosurgical current from the generator to a patient, the handpiece having switches disposed thereat for changing the level of the output power delivered from said generator to said patient whereby the change may be effected from the sterile field of a surgical procedure. The above switches together with cut and coagulation mode switches disposed at the handpiece are so connected as to minimize the number of wires needed to connect the handpiece to the generator. Decoding circuitry for determining the status of the switches is also disclosed.
