I found all that on Electrodragon... for very little money, waiting shipment to go out on monday, I will know more them, Their posted prices are good, Real Good.
Much as I dislike saying this, aside from a little experience, all of here pretty much use the same search methods. Here is a description of the switch you are looking for, I bought a dollar's worth (20) switches...20PCs Interlocking Self-Locking Switch [Types] – ElectroDragon I include the url to the switch so you have a better description of what you are looking for. Digikey and Mouser buy from the same distributors that most of Ebay (China) does FYI. This can make long term planning on manufacturing a device somewhat 'iffy' as if the Mfr quits making them the only thing you will buy is surplus inventory... which is about 80% of what Ebay sells.

I got my shipment from Electrodragon today Everything as described good quality PCB's and great looking parts. I paid a little extra for faster shipping but I was Still amazed at the quality and the prices were 1/2 of Ebay or less
