snap swivels?

hi all, newbie here! im having a go at making my own rigs.

are snap swivels only used for the end of the main line for ease of snapping rigs/lures etc or can they be used throught the rig like for attaching weights etc?

many thanks

you can use them but lead links are stronger for bigcast , use the crane ones the american ones are dangerious an open .

thanks, ill give them a miss, still new to fishing and had some american ones so thought id use them, i have plenty of normal swivels so they will do

Best bet is to call into your local tackle shop and tell him your looking to start making up your own rigs. They should point you in the right direction about what to get or not. If your based in Dublin pop into south side angling and they will help you out.

Glesga.... I presume your from there?
