A surgical instrument includes a housing, a shaft, an end effector assembly, and a circuit board. The housing includes at least one first electrical connector adapted to connect to an energy source. The shaft extends from the housing. The end effector assembly is disposed proximate a distal end of the shaft and includes at least one second electrical connector. The circuit board is positioned on the shaft. The circuit board extends from a proximal end to the distal end of the shaft and includes at least one proximal contact at a proximal end thereof configured to electrically couple to the at least one first electrical connector and at least one distal contact at a distal end thereof configured to electrically couple to the at least one second electrical connector to thereby electrically couple the energy source to the end effector assembly.
