I am getting ready to drywall the ceiling of my layout room.  I was showing my wife my progress and that I was getting ready to put up the ceiling and she asked why I couldn't just leave it.  I told her that the drywall would stop the dust from coming down through the floor above.  She asked about painting the ceiling to seal it up.  So my question is:  If I sprayed all of the ceiling, would that seal it up enough to keep the dust level down?  The walls of the layout room are drywalled and the concrete floor will be under foam padd

I am new to the hobby and I have a partially completed layout and some used electric switches.  I was going to buy some micro toggels to use with the switches but I do not know what amperage to buy.  I located some .4 amp and some .5 amp.  My power plant is .5 dc and .4 ac.  Which toggels will work?
