Minimal Panel Spacing T-Series Carling Switches?

------Question for TA201-TW-B Please Put your question below------
The drawings in the data sheet of the T-series switches do not show the full width of the part including the flange on the face, whereas the data sheets for the TTG parts do show the full width. Such that I can design a panel for these switches, how much space is needed between each 0.550" cutout?

Hello,
Welcome to the DigiKey tech forum. I sent a request for the flange measurement and will post the information when I receive it.

Outside edge flange dimensions are : 31mm X 17mm or 1.25” X .67”
