Bert, there should be some kind of electronics parts store there; we've even got one here. Mouser is good, but it's a lot better if you can take them in and make sure of getting the right ones.Rog also just mentioned that they are polarised, so there is only one correct way that they go in.
Over here a spring can also mean a rill, so I am wondering how in the heck does one dampen water?**BG**
