How to replace Light strike switches?

Question

Keyboard

I bought a bloody b254 keyboard that uses Light strike technology (4 keys), after a year and a half of work one of them fell apart inside, just crumbled. In fact, we couldn't find a replacement. The warranty is over, the store offers to contact the manufacturer, tech. bloody support is silent. Maybe someone knows where such switches are still sold or what can be put in return?

Answer 1

Buy the cheapest version of the keyboard with such keys as the donor one.
Or AliExpress, all of a sudden.
