I'll be in the process of planning my first real layout for quite some time, and in the meantime I've been setting up smaller layouts to test different aspects and scenarios. When I start my larger layout, I plan to use DC to power tortoise switched on Ross switches. Knowing that will be the case, I'm planning to use some LEDs elsewhere on the layout that will utilize the DC power and keep less of a load on my train transformers. With that in mind, I see some great uses for LEDs in a control panel. I want to experiment with indicator lights on the control panel to indicate when sidings are powered or not.
My question is this: Can I use a DPST switch and utilize one pole for track power (AC) and use the other pole to control the LED? The switches are rated for different loads DC and AC, but I haven't seen anything about whether it's safe to have both on the switch at the same time (of course not on the same pole). My understanding is that both poles should be isolated completely, but I'm hoping someone can shed some light for me as to whether this is safe or if there's a better way handle this that doesn't involve my track power and rectifiers.
