Inside a Nexa PER-1500

I was looking for double pole relays suitable for mains voltage and noticed that one such relay is almost as expensive as a Nexa receiver, which got me wondering how remote switches does it.

I had an unused Nexa PER-1500 that I chose to disassemble and found that it uses a single pole relay, which to me was a bit unexpected since then you won’t know if it will switch the live or neutral.
