   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.
