1. A surgical stapler comprising:
- an elongate body;
an end effector disposed on a distal end of the elongate body;
an alignment pin supported by the end effector, the alignment pin configured to transition between a first position and a second position, wherein at least a portion of the alignment pin includes a conductive material electrically connectable to an indicator circuit; and
a pin receiving mechanism including a conductive terminal electrically connectable to the indicator circuit and configured to accept the alignment pin when the alignment pin is transitioned to the second position;
wherein the indicator circuit is completed to activate at least one indicator when the alignment pin transitions between at least one of the first and second positions and the second and first positions.
