Then I removed the cone shaped plastic piece which i will not use for this project also i marked with blue arrows 3 small metal pieces that need to be straightened to make the hole slightly smaller so that the switch would hold securely. This step is done much easier if the whole metal piece is removed all i did was just wiggle it around and pulled it out.
Here is a picture of the button installed in that metal piece that i removed.
Me working
Here i soldered 2 wires to a switch, drilled small hole for LED and installed it
