There was some regret after buying the 8.5mm MHPS2283 switches instead of the 6mm MHPS2266 switches. It turned out there were a few 2266 switches in some doll hair LED lights which arrived before the age of 3D printing. They must not have been seen as useful, since no custom enclosure could be printed. Now that they can be used, they're garbage. They're just too small to give the satisfying click of the 8.5mm. They're also a lot more fragile & wouldn't last long. The 8.5mm were what we had in the 80's & they defined satisfying clicks for lions.
There is a need to build new remote controls for a camera, so the choice of switches has arisen again.
