I’m going to start using some slightly different values. Hole sizes come from recommended clearances for the bushing sizes specified in the datasheets. Pad diameters are based on washer diameters as measured since the datasheets rarely specify that:
- Jack: 9.8 mm / 14 mm (vertical e.g. Switchcraft 110X series); 11.4 mm / 15.7 mm (horizontal e.g. Neutrik ST-NMJ6HCD2)
- Rotary switch: 9.8 mm / 15 mm
- Pot: 7.4 mm / 11 mm
- Toggle switch: 6.6 mm / 11 mm
- Trimmer pot: 2.5 mm
