Ps Nice light switch, can you make them smaller?
The current PCB is about 45mm x 45mm it is perfect to retrofit in the light switch socket. You can integrate a bit more the UC componentes, but the components that are imposing the size is the main X2 capacitor, large'ish bypass caps, filter (the coil has to withstand 3A) and track clearance. I guess you could still shrink the design another 10mm x 10mm.
As far as the glass sheet is concerned, you can have it in any size. Perhaps the smalles size is that of the sensor PCB or the size of the wall switch potting box.
Looks beautiful! Where can I get more info on these? They use a microcontroller, so the OP may want to take a look.
Thanks for the comment, here is the flyer/catalog I pitched for the customer a while ago to present to him his reference design.
Those switches do look good but it appears they suffer the same shortfall with most commonly used loads.
Yes, I think that was what I commented in the first post. Driving incandescent loads is great and it works spotlessly. However, inductive loads, switched loads they don't behave as they should nor is it recommended. I tried it out with a good range of CFL bulbs with various degrees of success. For example, those sold by Ikea work well on all their CFL range. Dimmable CFLs work just as good as incandescent bulbs. For fluorescent lights is a big no, no (given how the load is driven).
For inductive load configurations you would need a separate phase feeding the switch's electronics which was the other configuration I developed for the customer (didn't say much about it because of the subject of the thread).
The last thing was that you can calibrate it to be touch or proximity sensitive (the latter is great fun seeing people do their Jedi swipe to switch on the light

)
Anyway, here is the "catalog" that went on as part of the final delivery hope you like it.
One thing I do love about the switches I have around the house is that I no longer need to clean finger marks around light switches

, and they do look very cool.
