I am sorry I can't help you. The box is with my elderly dad (95+) who lives out of town. He loves the box - the music chip did go bad and we had to replace it.

The only switch is has is off and on. If you want to play music of the sd card then you must unplug the audio cord from the music source. Interestingly it plays music off the sd card louder than music from an outside source.

Mine has a switch, it's located underneath by the battery. It's a small/tiny black switch.

No. It doesn't even have an on/off switch. Just plug it in and let it go. Or not.

No. There is no selection or switch. You just plug in and wait. It works fine for us.

Yes it does. The bigger white bar that you see on the switch is basically a big button. You can press it to manually turn the light on or off.

No, it has no switch or indicator. It switches at one speed, automatically, per it's design.

No built in switch...it uses the wall switch. It can be used lights up or down, though, if that matters to you.

Yes, There's an A,B or both A&B; Speaker switch that's right underneath the Power Button. Johnny

No, it does not have a physical switch - it is done strictly by keyboard. It is quite reliable too; I'd say that perhaps once a month I've had it lock up & fail to switch properly (and I think that it's my hitting an incorrect key) - pulling and re-attaching the cable brings it back online.

Yes. It has a very small switch on the side... center for off, up or down for green and blue. I have to admit though, it's just easier to unplug it

No. The switch is passive, a straight line in and out through a push-button selector.

Yes, but do not buy it as the off/on switch broke two days after the two month warranty was up

No it doesn't, but there is no way possible to purchase this switch anywhere else at this price! Buy it and spend a couple bucks buy some velcro I promise you'll be happy.

There is no switch on the back. I do not know if it has an internal auto-power select capability.

Yes, it does, It also has another cord to link it to a second unit, so it can be powered and switched from the same outlet. This light is very weak, even though you didn't ask that question.

Yes it does but what I don't like is that it does not have a switch for the low and high wattage.
