Hi all. Two separate projects which will need a relay of some sort to 
run from a Pi or similar.

I'm really looking for something plug-and-go rather than build-your-own 
(especially item 2 below)

First is a dpdt relay to switch around 12-20 V at a couple of amps. spdt 
are easy to come by; the only dpdt ones I've found are on aliexpress, 
but their longevity is possibly open to question :-{

Second is something to switch mains safely - a full 13A to run a 3kW 
heater. I've drawn a blank: best I can think of is to butcher one of 
those wireless mains switch modules, which would at least provide a good 
isolation gap :-)

TIA for any ideas.
