Claim:
1. A surgical instrument, comprising: a shaft having a proximal end portion and a distal end portion; an end effector disposed at the distal end portion of the shaft and having an end effector component configured to translate between a first position and a second position; a transmission mechanism comprising a motor and a drive system coupled with the end effector component to translate the end effector component between the first position and the second position; and a limit switch operably coupled to control the motor, the limit switch having a first state corresponding to a position of the end effector component between the first position and the second position and a second state corresponding to a position of the end effector component at one of the first position or the second position, wherein the motor has a first operating voltage in the first state of the limit switch and a second operating voltage in the second state of the limit switch, the first operating voltage being higher than the second operating voltage.
