A surgical instrument comprises a surgical end effector having an actuation assembly for effecting a surgical procedure when actuated, a handle mechanically coupled with the end effector, an electric motor disposed within a shell of the handle, and a power supply. A selective switching connection is disposed within the shell of the handle and electrically couples the motor to the power supply to selectively power the motor, wherein the switching connection has an unpowered state, a first powered state where a given power is supplied to the motor, and a second powered state where a power greater than the given power is supplied to the motor.
