Wiring

I am grateful for tips on wiring:

Room size 4x4 meters.
1 fused power supply.
3 switches and 1 dimmer.
6x 50 watt recessed spotlights (without transformer) in sequence.

How is it wired so that I can use on/off from each switch and the dimmer?

Cable colors blue - red - green/yellow

FURTHER INFO:

6 recessed spotlights are to be installed each with 50 watts / 230V ~ 50Hz - the spots are without transformer!

The "dimmer" I have and want to use is a light regulator 20-500VA (I just saw in the leaflet that it is a low-voltage halogen lamp dimmer) voltage 230 V ~ 50 Hz power 20-500 VA fuse T2A/250 V.

SPOTS and DIMMER are DO-IT-YOURSELF STORE PRODUCTS

Although I can switch the dimmer on/off, which I do not need, I only want to regulate the brightness with it (probably important because of wiring with the other 3 push-buttons)

HOW TO PROCEED NOW?

Well, I am not an electrician for building technology, but I think you would have to connect the dimmer to the supply line, so connected in a junction box. From there it gets difficult, I think. I believe you can hardly avoid a relay for that. But for something like that, it's best to hire an electrician to connect everything, because from my own experience, I know there are many potential sources of error here and a layperson can quickly run into problems with it.
