1. A surgical stapling instrument comprising:
an end effector defining a longitudinal axis including a first jaw and a second jaw, the first jaw including an anvil and, the second jaw configured to receive a stapler cartridge having one or more staples and a switch movably coupled to the stapler cartridge;
a drive member configured to translate distally through the end effector;
a staple cartridge;
a locking member movable from a disabled position permitting distal translation of the drive member to at least an axial position wherein the drive member engages at least one of the staples, to a locking position inhibiting distal translation of the drive member to said axial position; and
wherein the locking member is configured to move between the disabled and locking positions based on a lateral position of the switch;
wherein the switch is positioned within a slot formed on a tail portion of the staple cartridge and wherein the switch is movable in a lateral direction relative to the longitudinal axis, from a first position wherein the switch maintains the locking member in the disabled position to a second position wherein the switch disengages the locking member, wherein the slot includes one or more detents formed therein, the detents being configured to provide mechanical resistance when the drive member engages the switch.
