alignment notch should ensure the correct orientation of the
switch.

4 Install the black nut, with the square bezel facing you. Be
careful not to overtighten. Use an adjustable spanner to get
it tight such that the switch casing does not turn in the panel
when the switch is turned. If the notch was carved well, you
should not need to tighten it much to get it to hold steady.
