    Abstract: Electrosurgical apparatus for performing at least cutting and coagulation of biological tissue, which comprises a hand operated electrosurgical pencil comprising an electrically insulated housing and an electrode with a distal end defining a tip, means for supplying high-frequency, alternating current, electrical energy from a generator through the electrode to the tissue and means for returning electrical energy from the tissue to the generator to complete an electrical circuit, switching means mounted on the housing for selecting the cut mode or the coagulating mode, which switching means is connected to an isolated low voltage, direct current circuit which provides an appropriate signal to control the generator in the cut mode or coagulating mode, respectively, whereby the generator supplies the desired high-frequency, alternating current, electrical energy to the electrode and current leakage is limited.
