I assume you are refering to the clear plastic cube relays?
This is what I'm currently using in my small analogue circuit. So you
are confirming my initial plan of small relay linked to a larger relay
for the 120VAC?
What would be the specs for the smaller intitial relay (the one powered
off of a transitor)?
Thanks.
