The 4Amp is actually much more cost effective:

These seem like these should work, but I would hope someone else could concur before you spend your money.

Yes, it's "only" $3.49 (vs. $11.49)...but only switches DC loads whilst the more expensive part switches AC or DC (like a traditional relay). One of those considerations for Solid-State-Relays.

BTW, I seem to recall a thread about how-to-build a track-powered battery-replacement circuit for the 1.5V D-cell (?) in some kind of horn circuit. If that's the case here, perhaps there would be some way to combine circuits functions...
