I found Snap Circuits by Elenco while searching for a 15Amp switch for motorbike on maplin.
Looks lovely. Reviews on Amazon look good.
Only problem is maplin don't make credit card payments easy :(
To authorize credit card got email from maplin, phoned up credit card team.
Told to wait for access code sent via snail-mail.
It's two weeks now (Dec 3) have been so busy work/home haven't had a chance to phone them and find out what's up.
