M890G multimeter pictures of the selector knob

Hi. I am an electronics technician. I have an m890g multimeter and I have been working with this multimeter for many years, the plastic selector handle of the multimeter was broken and I opened the multimeter to repair it, but after opening some of the pins  Messi was uprooted and I do not know how to put them in their proper place, I ask you for help, if possible leave me a picture of the selector handle, thank you،My gmail address is sha.samani@gmail.com
