1. A surgical device, comprising: a device housing defining a connecting portion for selectively connecting with an adapter assembly;at least one drive motor supported in the device housing and being configured to rotate at least one drive shaft;a battery disposed in electrical communication with the at least one drive motor;a circuit board disposed within the device housing for controlling power delivered from the battery to the at least one drive motor;a loading unit configured to perform at least one function;an adapter assembly for selectively interconnecting the loading unit and the device housing; anda loading unit detection assembly disposed in mechanical cooperation with the adapter assembly, the loading unit detection assembly including: a detection link configured to be engaged by the loading unit, the detection link being longitudinally translatable with respect to the loading unit;a switch pin disposed in mechanical cooperation with the detection link, such that longitudinal translation of the detection link results in a corresponding longitudinal translation of the switch pin; anda switch button disposed in mechanical cooperation with the adapter assembly;wherein a predetermined amount of mechanical engagement between the loading unit and the loading unit detection assembly causes proximal translation of the detection link and causes the switch pin to move proximally into contact with the switch button, and wherein a predetermined amount of force exerted by the switch pin against the switch button activates the switch button, which electronically communicates with a portion of the device housing to permit actuation of the at least one drive motor. 2. The surgical device of claim 1, wherein a distal end of the detection link includes a camming surface for engaging a retaining lug of the loading unit. 3. The surgical device of claim 1, further comprising a switch link disposed between the switch pin and the detection link, the switch pin being longitudinally translatable with respect to the switch link. 4. The surgical device of claim 3, wherein the switch link is rotatable with respect to the detection link. 5. The surgical device of claim 3, further comprising a first biasing element disposed coaxially with switch pin, the first biasing element being disposed between a proximal portion of the switch link and an enlarged diameter portion of the switch pin. 6. The surgical device of claim 5, wherein the switch button is at least partially housed by a switch housing, and wherein the loading unit detection assembly further comprises a retraction pin disposed at least partially between the switch housing and a portion of the switch link, a second biasing element being disposed coaxially with the retraction pin and configured to exert a distal force against the switch link. 7. The surgical device of claim 6, where the second biasing element is configured to begin to compress prior to the first biasing element beginning to compress. 8. The surgical device of claim 6, wherein the retraction pin is longitudinally translatable with respect to the switch link. 9. The surgical device of claim 8, wherein the switch pin is longitudinally translatable with respect to the switch link. 10. The surgical device of claim 5, wherein the first biasing element does not begin to compress until contact is made between the switch pin and the switch button. 11. The surgical device of claim 1, wherein the switch button is at least partially housed by a switch housing. 12. An adapter assembly including a loading unit detection assembly, the adapter assembly configured to operably couple a surgical device to a loading unit, the surgical device including a drive motor configured to rotate a drive shaft, the loading unit detection assembly comprising: a detection link configured to be engaged by the loading unit;a switch pin disposed in mechanical cooperation with the detection link such that longitudinal translation of the detection link results in a corresponding longitudinal translation of the switch pin; anda switch button disposed proximally of the switch pin;wherein engagement between the loading unit and the loading unit detection assembly causes the detection link and the switch button to proximally translate with respect to the loading unit such that the switch pin engages the switch button, and wherein engagement of the switch button with a predetermined amount of force from the switch causes an electronic communication from the loading unit detection assembly with a portion of the surgical device to permit actuation of the loading unit. 13. The loading unit detection assembly of claim 12, further comprising: a switch link disposed between the switch pin and the detection link, the switch pin being longitudinally translatable with respect to the switch link. 14. The loading unit detection assembly of claim 13, wherein the switch link is rotatable with respect to the detection link. 15. The loading unit detection assembly of claim 13, further comprising a first biasing element disposed coaxially with switch pin, the first biasing element being disposed between a proximal portion of the switch link and an enlarged diameter portion of the switch pin. 16. The loading unit detection assembly of claim 15, wherein the switch button is at least partially housed by a switch housing, and wherein the loading unit detection assembly further comprises a retraction pin disposed at least partially between the switch housing and a portion of the switch link, and further comprising a second biasing element disposed coaxially with the retraction pin and configured to exert a distal force against the switch link. 17. The loading unit detection assembly of claim 16, where the second biasing element is configured to begin to compress prior to the first biasing element beginning to compress. 18. The loading unit detection assembly of claim 16, wherein the retraction pin is longitudinally translatable with respect to the switch link. 19. The loading unit detection assembly of claim 15, wherein the first biasing element does not begin to compress until contact is made between the switch pin and the switch button. 20. The loading unit detection assembly of claim 12, wherein a distal end of the detection link includes a camming surface for engaging a retaining lug of the loading unit.
