I need to manauly control a servo -

Hey guys its been a while but I need some help. I need to control a standard rc servo with a manual switch for a small robotic project. how do I go about doing this? internet is turning up nothing.
Ideally I would like it to be a toggle switch to operate by a hand.
this is gonna be a motorized front license plate for car shows. so it flips up under the bumper and swings down when I want it.
I have a parts list so far to do it digital vs analog
I'm on a work comp so I cant post up from ebay but here goes
1) dc-dc converter 12v/24v step down to 5v25w - water proof and heat sinked listing 140571118755 - $8.88
2) futaba 12" 10x extentions - $4.80
3)FUTABA S3302 1/4th scale servo. water proof and metal geared. 111ozin @6v (.58 foot pounds of torque) - $40.81 listing 251782909061
4)servo tester with manual pot control - $8.97 listing 381289302462
I know I've seen vehicles before with flip up license plates. From what I've been told is that they stay down when the vehicle is turned on then when you shut the car off the plate flips up. This seems like a lot of work to be able to control the plate yourself.
If you want a flip switch instead of the dial on the servo tester: I think it should be possible to use the right resistors. The dial on a servo tester is basically just an adjustable resistor, if you measure the ohm values it gives in the desired positions, you can replace it by resistors with those values and a switch.
Or maybe get some cheap 3 channel radio from hobbyking, throw away the transmitter case, steering wheel etc., put it in a small box and you have a radio-controlled license plate.
If you have a lowrider, you could also add a gyro to make the license plate always stay level when you let it bounce ;)
