How to connect the Rexant button in a car?

Boris asks:
There is an anti-vandal button Rexant ON-OFF Ø 12, 12V (2s) blue, with fixation. They are designed for switching electrical circuits up to 12V by pressing a button. Which terminals must be connected to the car's electrical system to turn off the cigarette lighter. There are 4 terminals on the switch, two long (+ and -) two short without marking.

The answer to the question:
Hello! Try on the long terminals, where + and - are indicated, apply 12V - I think that this is the button illumination, if the backlight lights up, then I'm right. Then cut the wire that goes to the cigarette lighter and connect it to the remaining two terminals (short without marking), that is, the button with these two terminals into the wire break.
