Opto Mosfet (SSR) equivalent circuit

[OBones]

How many did you want?

Two for a start, and maybe 2 more.
I went online to digikey, found the part I wanted for about 4$ per piece
which is a reasonnable price. But then I went to the shipping and
handling costs: 11$ shipping, 6$ handling (or something similar).
Heck, 25$ for two chips, it's a bit too much.
I'll keep nagging the official distributors in France, maybe one will be
so annoyed that it will send me two chips ;-)

I have to pass an order at digikey too.
We could share costs. Write me in private.

Well, I have the schematic ready, it's just that I can't find
those OptoMosfets. I may end up replacing them by a DPDT relay,
but it uses more amps, and that's not desirable (well, I could
live with it)

A relay is better at the side issues of overvoltage
and overcurrent. For reduced power use a bistable
maglatch relay, which only needs to be pulsed to
switch over. For best low level signal handling
choose a sealed relay with au-au contacts.
eg, Omron G6AK-234 series.

Thanks for that.
