I'm interested if anyone knows anything about a relay: em10 with details in
English.

Or any suggestion for a better group or other forum to ask in?

PS Not talking about plugs for walls ;-)

What do you want to know about it. the data sheet is fairly easy to
Interpret without any need for translation.

two pole changeover relay with 5v 150 ohm coil absolute max 14v drop out
voltage 1.5v
contact rating 40v dc 1amp non inductive
Inductive/AC rating 30VA 0.7a inductive

Anything else you need to know?
