Norton Cover, Switch
A rubber cover that protects the brake light switch on a Norton hydraulic front master cylinder assembly.
This is a switch cover for a Norton front brake master cylinder setup, part number 06-2524. The catalog places it with the handlebars and front brake master cylinder and hose group, where it sits over the brake light switch on the master cylinder to keep water and grit out of the electrical contacts.

It's a small rubber piece but it does real work protecting the switch underneath from corrosion and dirt, since that switch lives right out in the weather on the bars. Catalog records tie its appearance to 1975, and it's built for a hydraulic front disc master cylinder assembly rather than any drum-brake setup.
If you've got a Norton with a disc front brake and the rubber over your brake light switch has cracked, split, or gone missing, this is the part that closes that gap back up. Give the shop a call if you want to confirm it matches what's on your master cylinder before ordering.
