I use these small toggles for track power. They come with the leads attached which makes wiring easier. The small size takes up little room on a control panel.
Several different types of buss bars as well. For track power I'm using bare grounding bars (available at HD/ Lowes). They are made for electrical panels. Just mount them with an insulator between the plywood and the bar.
Switches and accessories go through barrier strips and euro-style terminal strips. Jumper bars can be added to the barrier strips to make the whole bar powered by the same source (good for track buss).
