Delayed electrical plug. Where can I buy?

Question

Electronic components

Good evening!
In short, I need some kind of cheap device, something like a time relay on an electrical plug, which would apply voltage a few seconds after it was energized.
In other words: I have a surge protector plugged into the 220V outlet. 4 electrical appliances are plugged into it. I need that when I press the button on the surge protector, 3 devices turn on immediately (as in normal operation), and the fourth voltage is applied only after 5 seconds (or 10), so that the device itself turns on later.
Are there options for how to do this?

Answer 1

If you have hands and a little knowledge of electronics, then the question would not have arisen, I suppose ...
accordingly, there may be no knowledge (do not take it as an insult!), Then you can try this:

cross the timer output to the input relay control + power + ground ... well, power for the device itself.
PS or look at something they have in the catalog ....
