I have a relay based audio line-out switching circuit. To drive the relays I was thinking of using a switch with an nMOS, but the issue was that when the switch is floating, both nMOS can conduct. I was thinking of cascading 2 nMOS's to operate like a pMOS since I can't find one that conducts at logical level in my area. I added a schematic below.
