Abstract
A motor-driven surgical instrument having a control assembly for controlling a switch of the instrument. The surgical instrument may comprise a motor control circuit, a drive member, and a slider. The drive member comprises a first shoulder at a first position and a second shoulder at a second position. A first portion of the slider interfaces the drive member such that the slider is moveable in a direction of movement of the drive member when either the first shoulder or the second shoulder of the drive member engages the first portion of the slider. A second portion of the slider actuates a switch of the motor control circuit when the drive member moves the slider to a first position relative to the first switch. In various embodiments, the switches of the control circuit are not embodied as a part of an IC.
