The snap switches are not Atlas' best offering, but they can be made to work reasonably well. However, be sure that your rolling stock wheels are all in gauge as well, since that is the "other half" of the equation. If you do not have an NMRA gauge, now is the time...!
To get the snap switches to work better...
1. Check all the appropriate dimensions with your NMRA gauge - flangeways, gauge of track, etc, etc.
2. Check to make sure the rivets that hold the pivoting ends of the point (movable) rails are snug, but not too tight. A **light** tap with a punch and a hammer can tighten them up if needed, but BE CAREFUL! (Do not do this when you feel like this - :curse: - or you may have to throw out the turnout

)
3. Check to make sure that the point rails are in good shape. Since they are made from bent metal, as opposed to real rail, they can sometimes fall over or get bent slightly. Also check the ends that are trapped in the throw bar to make sure there is not too much play. As long as the throw can hold them tight to either side, there should be no problem.
4. If the point rails are not tight to the stock rails when trown to either side, bend or file them for a better fit. You can also (slightly) notch the stock rail so that the point rail snugs right into the side of the stock rail. Also file the end of the point rail to give it a bit of a rounded end so it is harder for the wheels to "pick the point".
If you are using the Atlas switch machines in combination with the turnouts (snap switches) then the advice about having things well secured is good. Since the little slug snaps back and forth with quite a bit of force, you need to make sure that the machine itself and the turnout are not moving so that the full force of the motion goes to throwing the points, not moving the whole turnout.
Hope that helps.
