You can buy a much better quality insulated solderless connector(s) from
www.allelectronic.com in a variety of terminal sizes and for any wire size from 24 to 10 gauge. If you're planning on using lots of solderless connectors there's a racheting crimping tool made by Palladin Tool that is far, far superior to the regular "crunch plier type". Last price I saw on the Palladin was just under $20. Between you me and the sign-post, most of Atlas' electrical stuff is pretty cheezy. You can get better wire cheaper at Home Depot or Lowe's or many,many surplus electronics places. All the "selector" and "terminal" switches wear rapidly and then make poor or intermittent contact. They are easier to wire than regular toggle, rotary, or slide switches, but you pay for the convience with so-so quality. Soldering feeders to the outside of flex-track is far superior to the terminal joiners, even though it takes a little practice. If you're just starting out, the Atlas stuff is OK, and takes a lot less "thinking" about what kinds of switches you actually need. But most people "out-grow" the Atlas switches and go to industrial quality toggle and rotary switches and pushbuttons, or go to DCC and rip out miles of wiring that becomes unneccesary. Just thought I'd mention your options.
