Tracy,
If you are wanting to manually control the servo, then maybe you could use a basic servo tester to operate the servo..??

Change out the rotary pot for a switch, and the servo tester should move the servo up and down, and HOLD it in the set position (either up or down).. A on/off/on switch would be a good idea to help save some battery power when the legs are up..
The only extra thing that you would need to do is add a battery pack to run the servo tester..
