Abstract
A surgical cutting and fastening device is disclosed including a handle assembly, a power supply, and a control circuit. The handle assembly includes a motor configured to drive a cutting member. The control circuit operably couples the power supply and the motor. A firing switch allows the power supply to provide power to the motor in a first energizing direction. A forward control circuit is configured to control current flow from the power supply to the motor. The forward control circuit includes a first flow path and a second flow path including a power control switch. The power control switch prevents current from flowing through the second flow path. The power control switch allows current to flow through the first flow path and the second flow path. A reverse flow path is configured to allow the power supply to provide power to the motor in a second energizing direction.
