Solenoid actuated turnouts require MOMENTARY power ONLY! If connected directly to a power source for more than a few seconds, the solenoid will burn out! In order to make the turnout points shift from one route to another, you need either two pushbuttons, one for each solenoid, or a single pole double throw (SPDT), center-off springloaded toggle switch. One wire from each solenoid can be connected to each other in common, but the other wires must go through the momentary contacts. When I can get them, I will use a two-position rotary switch mounted on my control panel on the diagram, with the pushbutton located next to it. The rotary will indicate what route the turnout is aligned to, and the button actuates the selected solenoid.
Hope this helps.
