    I would like to make a five minute delay for some headlights and I would like to use a momentary pushbutton.

    A simple timer using a 555 chip, or cd4060.

    Do you have a different way that would not require soldering?

    Which one? The datasheet for a specific time delay relay would show the connections.

    I would like to use a momentary switch and delay it for 10 minutes but I don't know how to keep power with a momentary switch.
