The Light & Horn Switch with P/N 61 31 8 048 162 does not properly fit on the Clutch Lever Assembly with P/N 32 72 2 072 112
The cause of this problem is clarified in the photos below.
The ends of the switch housing extend too far into the clutch lever assembly.
As soon as both parts are mounted together on the handlebar, the switch housing is pushed outwards, so that the switch housing can no longer be hooked behind the cam.
Option: you can grind down the corners a little to make the housing fit. Because it’s a brass housing, this won’t lead to corrosion, and the corners won’t be visible after installation.
All BMW parts suppliers obtain this switch from the same manufacturer, so there is no alternative.
