I have a 3.3VDC output from a developer board that I need to use to control the 24VAC coil of a definite-purpose contactor (like one you'd have in an air conditioner).
I could use something like this:

but then I have another relay, and need to supply another DC voltage.
Any elegant way you can think of to get from 2mA @ 3.3VDC to ~7VA @ 24 VAC?
A latching or flip-flop arrangement would be even better...
Thanks,
Heath
