"Get to know your tools"
any ideas why the led is not lightning when i press the switch?
when i connect the led directly without using the switch it works fine but when i use the switch it dont work any ideas ?
Try turning the switch 90 degrees.
i tried it will not fit if i turn it
anyway i forced it to fit and it ddnt worked
Are you sure the LED isn't connected backwards?
Also, sometimes it seems that those pushbuttons can't make a good contact with the breadboard's contacts... Or maybe the button is not working, can you check it with a multimeter?
the led is connected correctly (i tried direct circuit without switch)
i tried i pushed the switch strongly i thing it touched the breadboard
how can i check a switch with a multimeter ?
Put the multimeter in continuity test and touch the 2 contacts of the button. No sound is emitted. Push the button and repeat: the multimeter should beep.
If not, then either you're testing the wrong contacts or the button is not working properly.
Try temporarily replacing the switch with a piece of wire.

Can you post a photo taken DIRECTLY ABOVE (DEAD CENTER) the circuit (as is the STANDARD OPERATING
PROCEDURE for circuit photos)

I'm surprised at you encouraging photos 
Make a pencil drawing of all the circuit connections and post a photo of the drawing.

I think the legs on the switch are just not long enough to reach the contacts in the breadboard.
broken push button 
that's it
put the button on same side as led, turn it it will fit as the distance is correct.
as there are 4 pins you have many possibilities
