Some penetrating oil and a few back and forth movements make this joint again free. With benzine or similar solvents and q-tips remove all old, resinous fat residues and do not re-oil them. In the case of the switch itself, make sure that the black switch pin is also very easy to move and is not greasy, otherwise it should be replaced. The switching is triggered by light pressure on the switching pin (test with toothpicks or similar) and is accompanied by a click sound.
Jeśli to poczyszczę i posmaruję na nowo tym olejem i nie będzie działać wtedy sprawdzę tą opcję z kondensatorem.
