I'm a big fan of the TSW series touch panel from Crestron. I have 4 of them in my condo at the moment. 2 of them are on my and my wife's night stands. This model doesn't offer tactile buttons so when I wake up in the morning and want to turn the lights on, I need to physically look at the touch panel to do that.
Since the touch panel has 5 capacitive buttons on the right hand side of the panel I just needed to give them tactile feedback. So a few weeks ago I purchased capacitive suction cup buttons for smart phones and found that they work great on the touch panels except they fall off after 30 minutes or so.
Tonight I designed a prototype plate to fit on the touch panel and stuck the buttons inside the plate. An hour and a half of my time to measure, design, and print a great addition to my touch panels. Take a look at the results. It will need a little fine tuning and a reprint in black. But for a prototype this works great.
