I've purchases for my son an EZ track N scale system and purchased some extra track and four swtiches, so I could build one of the layouts shown on the box. My issue is that the train stops when entering any of the swtich zones. I have not yet connected the switches to the power supply and understand they need to be powered for the trains to work on these sections of track.

What I can not determine is how to connect them together. I can easily attach the switches to the track but not the power supply. I envisioned powering all of the switches in series and then running one set of wires into the power supply but none of the connectors are the same meaning the power supply appears to require bare/stripped wires, the switch cables have medium sized crimped blades, and the switch boxes require some sort of connector in a plastic housing on one end and what appears to be a really small metal blade connector on the other end. I've look at muliple websites looking for a picture or even an electrical diagram to confirm how the switches should be connected figuring I would then need to cut off the various connectors and simply hard wire everything. But I can't find any diagrams. Any one have something they can share or suggestions to avoid removing the connectors and going the hard-wire route?  Any idea why these EZ track accessories don't easily connect to the EZ track power supply? Seems very confusing for what should be very simple and in fact EZ.
