Abstract
An electrical switching system for use in various types of electrosurgical instruments and related tools comprises a system adapted to automatically determine which of at least two electrical current modes to deliver through an electrosurgical instrument based on a condition sensed by the electrosurgical instrument. In another embodiment, the electrical switching system comprises a generator, the generator including a first electrical distribution systems for delivering monopolar electrical energy, and a second electrical distribution system for delivering bipolar electrical energy, a controller coupled to the generator for selecting based on an input which of the first and second electrical distribution systems to activate.
