Model: KXM-2.Steps: 24.Gangs: 4.Formal switch configuration: 4P24T.Shaft Type: D-type 6mm diameter.Orientation: flat side pointing at step 1.Rotation: clockwise.Angle of rotation: almost full 360º rotation at step 24. About <15º/step. Could not measure.[Changelog]* Update v3- Modified circular patter of pins from 160.5º (rough visual estimation) to 160.320325º (exact) since I forgot to change my Fusion 360 decimal precision to 6 decimal places. This should improve tolerances if you need to make a PCB and you have to rotate the pads.For reference: pad angle offset from Y-axis is 9.839838º and pad-to-pad angle is 14.574575º.2x pad angle offset from Y-axis + 11x pad-to-pad angle = 180.00001º.* Update v2- Thread changed from M8 to M9 due to previous wrong measurement.- Distance from alignment pin to center of shaft corrected to 12mm.Commonly used as a DIY alternative for audio volume control using discrete steps, aka. a stepped attenuator.I recommend using my spreadsheet you can find in this OneDrive link (https://1drv.ms/x/s!AlYj338-mMvTg_NDXDJjs37PwkLnmA) to calculate the resistor values of a 24-step shunt attenuator. Save the spreadsheet and edit it afterwards.
