Is the 3V control signal the only power source or do 
you have higher voltage/current available?

If you have other power (+6 or 12V) simply use the 3V 
to forward bias a 2N2222 to ground the relay coil 
connected between the collector and the other power.

If not, you can switch a solid-state relay with ~3V.
