An electrosurgical system comprising: a handpiece (120) including: (a) a first power connector (52, 52A, 52B, 52R)； (b) a second power connector (52, 52A, 52B, 52R)； and (c) one or more moveable members having a first position and a second position； and an activation circuit (300) having a first switch state (310) and a second switch state (312), wherein the activation circuit (300) in the first switch state (310) does not allow either a first electrosurgical therapy signal or a second electrosurgical therapy signal to exit the handpiece (120)； wherein when the activation circuit (300) is in the second switch state (312) and the one or more moveable members are in the first position the activation circuit (300) allows the first electrosurgical therapy signal to exit the handpiece (120) so that a first therapy current extends between the first power connector (52, 52A, 52B, 52R) and the second power connector (52, 52A, 52B, 52R), and wherein when the activation circuit (120) is in the second switch state (312) and the one or more moveable members are in the second position the activation circuit (300) allows the second electrosurgical therapy signal to exit the handpiece (120) so that a second therapy current extends between the first power connector (52, 52A, 52B, 52R) and the second power connector (52, 52A, 52B, 52R).
