CONTROL CIRCUIT OF A SURGICAL DEVICE WITH A SWITCH AND A METHOD FOR DETERMINING THE STATE OF THE SWITCH

摘要

A control circuit (1602) of a surgical device (1600) is disclosed. The control circuit includes a first circuit portion coupled to at least one switch operable between an open state and a closed state. The first circuit portion communicates with a surgical generator (102) over a conductor pair (112) to receive a control signal to determine a state of the at least one switch.
