I'm a newbie when it comes to electronics. I need a very simple circuit that delays the input signal (12V) in 5 seconds (doesn't need to be very accurate). Yes, I know that in this forum there are many topics talking about "time delay" but I considered them a little bit complex to me. Can anyone help me with an simple electric diagram. Thanks in advance

What is the load that the timer is switching? Is one end of the load tied to ground or to +12V?

That needs to be specified so as to suggest something.

This is the current circuit:

My objective is to when I turn on the switch the light bulb only turns on approximately 5 seconds after.

Do you want it to remain on, or switch off by itself? Your first post suggests you want it to shut off after a certain amount of time, but I just wanted to clarify this.

If it could switch off by itself it would be better

If you want to be able to control when to turn them off, via the same "switch" as the whole circuit, then what you are looking for is called a "delay on make" circuit

And if it turn off at the same time that I turn the switch off??

yes.

The switch powers the timer and the light.
