I use a cheapo DIY store router for the comb-joint jig which just has an on/off switch, but have a more upmarket more powerful De Walt router which has the type of switch that you refer to John. It's in one of the handles - I have to twist it and hold it on and the moment I let go, it switches off. I guess it's a safety feature - a sort of 'dead man's handle' and means that you can't easily get your hands near the business end of the router with it still running. As has been said, the easiest option would be a tie-wrap to keep the router on all the time, and turn it off at the wall switch when you've cut a row of slots.

As to suitable wood, I guess in your case John, the problem is to find something for the lid that's an acceptable match for the cabinet. I tend to scavenge bits of oak and mahogany from old furniture or flooring offcuts, and cut them down to 1/4 thickness or thereabouts on my bandsaw, then sand them on my belt sander. I use plywood for the bottom (and top too, if it's a lidded box), often used on the rear of old chests of drawers etc.

I finish them with spirit stain and a couple of coats of shellac sanding sealer then paste-wax polish. Time consuming to say the least, but very satisfying nonetheless, and for me, a nice way of blending two complimentary hobbies - electronics and woodworking.
