pick away clive mate
this is what I need so I welcome any advice mate. Before I made that sort of ball on the top I filled the hole underneath with solder, then tried to get that dome shape just for neatness, but I did fill the prong on the switch. Not to sure if I soften the solder I can do much else

Are you applying the solder to the iron and then putting it on the part if so that is wrong. You need to put the iron on the part and then apply the solder to the part and you should see it flow. Some people when learning just dab the iron but the part needs about 1-2 secs of heat depending how big the iron is.

No mate, I watched a few tutorials on youtube, I held the tip of the iron against the prong on the switch for a short while then placed the wire against the prong, as soon as it melted I let it fill the hole till about 3mm, then I removed the wire and slowly lifted the iron away to leave that dome shape. I was also careful to keep the end of the iron clean with a special sponge I bought from maplin. I never realised just how fiddly soldering is! and time consuming,

But when did you apply the solder?

[ravihotwok]

time wise? think it was about5 - 8 sec? not too sure if im honest clive mate, but when it was melting plenty seeped in

Are you using lead free solder?

[ravihotwok]

No think its 60/40 lead but would have to confirm
