I bought several of these cheap push buttons from r. shack. For some reason they wanted an unreasonable amount for the ones with the housing, so I decided to make my own (take that, r. shack! -lol) . Anyway, it shouldn't be that diffult to create your own push buttons from scratch if you decide to undertake the task. You will only need a spring, some scrap metal, and wires. The housing will fit any push button enclosed in a 10x10 plastic container. Enjoy!
