dfk41 Ah I see. It’s quite possible that your Chinese switch didn’t have any balls to start with. 😳. Mine did come in a box with the cone wrapped in bubble wrap, but the switch was just in the box so I thinking the ball got dislodged in transit maybe the courier was playing football with it because the bag & box were pretty bashed up, which made me fear for the cone when I saw it
My Chinese switch was in the van, which I’ve just got back from the garage so did a comparison. Apart from some very minor dimensional differences externally both switch bodies have the ball retainers. (Chinese switch on the left)
However, the ball in the Chinese switch is only 12.7mm so ½″ in English compared to the 14mm ball in the Hario version & it pops out of the switch body much easier as a result. So I might get a 14mm ball ordered & replace it
