A cut-out switch of this type is the kind of component that used to manage the connection between the generator/dynamo output and the battery, opening the circuit under certain conditions so the battery doesn't discharge back through the charging system. Beyond that general function, our records don't spell out more detail on this specific part.
The catalog entry doesn't tie this to a specific model or year beyond the 1969-1970 span it appears under, and it doesn't state material, dimensions, or mounting specifics. If you're trying to match this against what's on your bike, give us a call and we'll confirm before you order.
