How to control two LED strips with a two-gang switch?

Question

Do it yourself

I want to make lighting of two adjacent rooms with an area of ​​​​3 square meters. I settled on LED strip. It turns out that there are only two tapes that need to be controlled separately by a two-gang 220V switch.
What is the best way to do it: power each tape from your own power supply and not bother, or still somehow come up with one? I would like to save money, get by with one PSU. Can this be done somehow?

Answer 1

• Put another one-key (or three-key) - to turn on and off the power supply, and switch the tapes through a two-key.
  
• Another option is two relays for 220V with two groups of normally open contacts. The relays are connected in parallel, the first group of contacts of each of the relays are parallel to each other and turn on the block. The second group of contacts of each of the relays includes each of the tapes.
  
• Another option - the first switch turns on the block, the second - the tape. It will not be possible to manage each fully separately (you cannot turn on only the second one), but this is the easiest
