look for mercury relay with contacts able to withstand main line (230V) 2/4 A with isolation > 400V;
Any help ?

Why toxic Mercury??
400V 4A is not even a tough spec for a mechanical relay. In fact I would study an "air conditioning contactor". My A/C compressor relay (contactor) switches 240V 6 Amps many times a summer. Yes, it CAN burn-out, but can be replaced for $18 at the local warehouse or depot.
BTW, even people who still sell Mercury advise moving to Solid State, 2nd link below.

I remember Years ago there where stair light automatics with mercury relays inside. Perhaps You can find one in an old building.
Does 30A suffice ?
