Excellent model railway wiring diagrams - Join a twine from each selector switch to the south rail of the block of tune you wish it to manipulate. Connect all of the wires which attach to the north rail collectively. Connect them to the alternative cord from electricity p.C. A and non-obligatory energy % b.
The selector is largely for wiring 4 blocks, unmarried pole/double throw (spdt) so the transfer routes one wire of the two from the block both to cab a or cabb, with a "middle off." ?the extra blocks you have the extra selectors you line up, once more with common rail for the opposite rail.
The controller is extra for opposite loops and possibly turntables and wyes and looking to describe the double pole/double throw (dpdt) wiring for not unusual rail is past my prose abilities. ?it's far all explained properly in andy sperandeo's book on wiring, which kalmbach has allowed to go out of print (for the ones doing dc wiring their new e book from larry puckett is frankly no substitute for the sperandeo e book, which in turn is dated and now not useful anymore for dcc discussions).

The atlas selector and controller are supposed for 2 rail trains, but the use of the commonplace rail method of wiring blocks. ?they arrive with excellent instructions on the way to use. ?at one time atlas published a very good wiring ebook tailor-made (of path) to their merchandise and it includes schematics for each. ?mine is from 1958 and i have not seen what they offer now.
Use insulated rail joiners to create electrically remoted blocks for your song. I generally create a new block from each fork in the street via the usage of the insulated rail joiners on both tracks after each turnout. You may find the more blocks the better. You may join collectively any range of selectors.
