Beebest F1 flashlight 18650 - 22650 rechargable battery fit with new switch holder

The original Xiaomi Beebest F1 can't use 18650 lithum rechargable battery due to short height because the spring and casing limited. So I designed this one to make extra room which helped the beebest f1 being able to use 18650-22650 lithum battery.
 

Check the orientation in the images to assembly the switch correctly

Note that this one is tight fit, so you have to use some force to push it in, and then it will stay there sturdy.

How to remove the switch from casing?
1. Remove the switch casing from main body

2. Hold the switch casing then push the button out

Just watch the video on how I assembled it.
