MOSFET for sure, pic related. Note that the 0V rail for both systems is connected together, if you need it to be isolated you'll instead have to use an optocoupler. If the load is inductive (like a motor) you'll need an antiparallel diode across it.

But I highly suspect you're doing something terribly, since you're switching 1.5V separately from a superior 5V supply (basically nothing under the sun runs on 1.5V without first stepping it up).
