#146224 - zero crossing switch
Responding to: ???'s previous message
Would a properly designed SCR circuit to replace the relay fix this problem?
there are oodles and bunches of zero crossing switch modules out there, I doubt you can do better (technically or economically) than buying one.

for reference, here is a type grabbed at random from the digikey catalog
