Hello claudiafer
There was no switch included with our purchase.
We use this switch (which is apparently not available from digitec at the moment):
Philips Hue dimmer switch
If I remember correctly, you can't change the colour with it, but you can set up colour profiles in the app, for example, which can then be activated with the switch (by pressing a button several times).
We use the Hue Bridge (if this is relevant).

Hello, the Philips Hue White & Colour Ambiance Infuse lamp does not come with a dimmer switch. You will need to purchase the dimmer switch separately. Here are some options you can consider:

1. Philips Hue Dimmer Switch: this switch allows you to dim the brightness and select different preset light scenes.
2. Philips Hue Tap Switch: This switch has buttons for up to four different scenes and does not require batteries.

Yes, you can adjust the colours of the lamp. However, this is mainly via the Philips Hue Bridge and a smartphone app. If you want to control the lamp without a smartphone, the Philips Hue Dimmer Switch or the Hue Tap Switch could be a practical solution.

The lamp is ideal for a children's room as it can create soft and colourful lighting effects that create a cosy atmosphere.

I hope this helps you.

Most Hue models include a dimmer switch (otherwise you can order it later)
Colour control only works with app!
Remote control can only do b/w
My experience shows that colour is usually not necessary at all... you can actually save yourself the extra charge.
