down button suddenly stops functioning!

Hey, i have a few broken tact switches and would rather not buy a new PCB board (especially since i cant even find one anywhere, they are all out of stock) Does anybody know if you can take Tact switches from an old PCB board (that are still good) and put them on a new one?

tact swiches are only a few cents if you buy them in a hardware store (dont buy them on mpc-stuff.com, prices are an brazenness)

Thanks DrNibbert. I checked out my local radio shack and found the tact switches for cheap but the leads were too short to fit through the circuit board. So what i had to do was desolder the tact switches from my old PCB and transferred them to the new one... worked liked a charm, and i have never soldered anything in my life!
