Reply to "20A switching relay"

The relay in your link is the one I was referring to. It is a DC relay though you would only have to add a diode in series with the coil if you wanted to power it with track power. This could actually work to your advantage. You could use one of the inexpensive buck boost convertors to power the relay. That way the relay would work both in Command mode with 20v AC on the track or much less like 7-8 volts AC in conventional.

If this was not being powered from track power you could use any source of DC like a cheap HO power pack or old desktop computer power supply.

Not sure how many relays you need. These relays can be had at any auto parts store for around ten bucks. Lots of cars and motorcycles use them. Just make sure they are rated for at least 30 amps. If you only need one it may actually be cheaper as you would save shipping. If you need a dozen then allelectronics is the place.
