An adapter assembly configured to be coupled to a surgical loading unit includes a switch, an elongated member, and an annular member. The switch is configured to be toggled in response to the surgical loading unit being coupled to the adapter assembly. The elongated member is in communication with the switch and is resiliently biased in a distal direction toward a locking position in which the switch is toggled. The annular member is disposed adjacent the elongated member and is rotatable between a first orientation, in which the annular member prevents distal movement of the elongated member, and a second orientation, in which the elongated member moves distally to toggle the switch.
1. An adapter assembly configured to be coupled to a surgical loading unit, the adapter assembly comprising: a switch configured to be toggled in response to the surgical loading unit being coupled to the adapter assembly;an elongated member in communication with the switch, wherein the elongated me

The adapter assembly according to claim 2, wherein the adapter assembly further includes a biasing member engaged to the annular member and configured to resist rotation of the annular member from the first orientation to the second orientation. 4. The adapter assembly according to claim 3, wherein the biasing member is a leaf spring having a fixed proximal end and a distal end in engagement with the annular member, wherein a rotation of the annular member pivots the leaf spring about the proximal end thereof. 5. The adapter assembly according to claim 1, wherein the annular member includes at least one appendage configured to abut the surgical loading unit upon coupling the surgical loading unit with the adapter assembly. 6. The adapter assembly according to claim 5, wherein the at least one appendage includes a first tab circumferentially disposed on the annular member and a second tab circumferentially disposed on the annular member and radially spaced from the first tab, the first tab being engaged with a distal end of the elongated member when the annular member is in the first orientation. 7. The adapter assembly according to claim 1, wherein a proximal end of the elongated member includes a ring member configured to toggle the switch when the elongated member is in the locking position. 8. The adapter assembly according to claim 7, wherein the ring member is proximal of the switch and not engaged therewith when the elongated member is in a non-locking position. 9. The adapter assembly according to claim 1, wherein the adapter assembly further includes: an inner housing having a proximal end, the elongated member having a proximal end disposed around the proximal end of the inner housing, wherein the switch is disposed within the proximal end of the inner housing; andan actuator board attached to the proximal end of the inner housing and extending proximally therefrom and overlapping the switch, the actuator board being resiliently biased toward a position in which the actuator board is spaced from the switch, wherein the proximal end of the elongated member biases the actuator board into engagement with the switch upon movement of the elongated member to the locking position. 10. A surgical instrument, comprising: a surgical loading unit having a proximal end including at least one protrusion; andan adapter assembly having a proximal end configured to be coupled to a handle assembly and a distal end configured to be coupled to the proximal end of the surgical loading unit, the adapter assembly including: a switch configured to be toggled in response to the surgical loading unit being coupled to the distal end of the adapter assembly;an elongated member having a proximal end in communication with the switch and a distal end, wherein the elongated member is resiliently biased in a distal direction away from a non-locking position and toward a locking position in which the switch is toggled; andan annular member disposed adjacent the distal end of the elongated member and including at least one appendage configured to abut the at least one protrusion of the surgical loading unit upon coupling the surgical loading unit with the adapter assembly, wherein the annular member is rotatable relative to the elongated member between a first orientation, in which the at least one appendage is engaged to the distal end of the elongated member to maintain the elongated member in the non-locking position and a second orientation, in which the at least one appendage is disengaged from the distal end of the elongated member such that the elongated member moves to the locking position to toggle the switch. 11. The surgical instrument according to claim 10, wherein the annular member is resiliently biased toward the first orientation such that the annular member rotates to the first orientation upon a decoupling of the surgical loading unit from the adapter assembly. 12. The surgical instrument according to claim 11, wherein the adapter assembly further includes a biasing member engaged to the annular member and configured to resist rotation of the annular member from the first orientation to the second orientation. 13. The surgical instrument according to claim 12, wherein the biasing member is a leaf spring having a proximal end fixed to the adapter assembly and a distal end in engagement with the annular member, wherein a rotation of the annular member pivots the leaf spring about the proximal end thereof. 14. The surgical instrument according to claim 10, wherein in the locking position, the at least one protrusion is captured between the at least one appendage and the distal end of the elongated member such that the surgical loading unit is lockingly engaged to the adapter assembly. 15. The surgical instrument according to claim 10, wherein the at least one appendage includes a first tab circumferentially disposed on the annular member and a second tab circumferentially disposed on the annular member and radially spaced from the first tab, the first tab being engaged with the distal end of the elongated member when the annular member is in the first orientation. 16.
