    Hi all,

    I am hoping someone can point me to some good quality relaible relays...

    I am after a 12V DC coil - 230V AC 15 to 20A max current of the DPDT type. I am preferably looking for the ones I can push the pins into a piece of stripboard and solder

    I am also after a 230V AC coil - 230V 10 - 15A max current of the DPST type...again I am looking for ones I can push into stripboard/prototype board and solder

    I am in the UK

    Thanks

    Not likely. 20 amp relays typically use .156" or .25 inch connectors (in USA). You just can't reliably jam 20 amps through a wire 1mm in diameter, so they don't build 20 amp relays like that.

    As an alternative, there are a lot of relays that have sockets for them so instead of strip board you could use sockets.

    Just looking at the plug in power relays...trouble is I cant find a 12V coil with 15+ Amps and 230/240/250V load contacts

    I havent really looked but im pretty confident I will find some with a 230V coil and 10A 230/240/250V contacts

    How about these?

    http://www.newark.com/finder/66-22-9-012-0000/relay-pcb-dpdt-30a-12vdc/dp/35M2031

    Had a quick look at the data sheet and there seems to be a little oddity about the current rating. The NO rating is 30A/50A max and the NC rating is 10A/20A max. Not too sure what is going on there, but they somewhat meet your requirements. I'd be careful with putting that amount of current on a stripboard though.

    This is prooving to be a real pain..just spent another 45mins looking. if not DPDT then DPNC is what I could go for but the NC must be around 15A

    Had to do it a different way where I use an extra relay so it can be done with 2 x 12V and 2 x 230V relays. I got the plug in power relays as they look like they have screw terminals and I should be able to stick them to the back of the box
