I just found these 11 mm dia button switches. I ordered 10 and received
them in less than 10 days. They are self illuminated, dimmable and glow
just enough that you can always see them in the dark. For about 6$. Check
them out at Alibaba.............

"S1004 led round light switch work by simply reducing the voltage supplied to the lamp, Which results in a light output decrease of the light"

Not to be a downer, but without PWM those are likely going to kill the life of your LED's.
If they dim by lowering voltage (as it says they do) the current is going to increase to compensate and your going to end up burning out your led's in short order.
This method works for 110V bulbs, but not for LED's. Unless you're running them from a constant current driver.

PWM switches power on and off at high frequency dimming the light while keeping the voltage and current the same.

I could be wrong of course.

I don't think the current is going to increase. The reason varying the voltage doesn't work is because the LEDs don't dim very much before they just go completely out. They are either on or off. Somewhere around 10V or 11V or so they just turn off. The PWM turns them on and off too fast to see and changes the percentage of time they are on vs off.

You don't think it's PWM? the fact that there are two wires in/two wires out made me think they were
