Problem with Karlik LWP1 light switch repair - Need help with missing element

Hello,

I have an unusual problem. Today I dismantled the light switch and I lost one element that I do not know how to fit inside. Maybe someone once had a similar problem and coped with it. The switch is Karlik LWP1. I put photos of the center and this element. I've been struggling with this for several hours and have no idea how to fit it

Store: new switch, about PLN 10, divided into several working hours ...
If you want to fix it, take it off the wall, it will be horizontal, it will adjust to the correct position. With contact up, cam down.

And where is the element that changes the contact position? "That thing" that you dismantled is missing.
Show the tip, maybe it will be possible to deduce how this contact should be mounted.

The missing part has a spring on one side (on the contact side), and on the other side it is empty (empty).

After a moment's thought, I finally figured out how it works It turned out that this element must be positioned with the contact facing upwards and the cam must fall into the hole of this other contact (thanks to qadam12). Then I put a second plastic element with a spring on it, setting the contacts in the appropriate position (so that the switch can touch or disconnect), click it and everything is fine
