I done fuct up. I ordered 15 rotary encoders after what I thought was extensive research but I missed one little detail. Built in switch? Check. Multiple detents? Check. 6mm shaft? Check. Threaded for panel mounting? Uh, no. Shit.
Maybe I can get a die and thread them, otherwise I’ll either have to rig up a PCB or glue them in place. There has to be a better alternative than buying different ones at four times the cost.
EDIT: I found another supplier that has what I need for about 50% more. I guess this is what I get for ordering stuff at 4 in the morning.
