Original CEV light and horn switch. Came stock on some Vespa mopeds including the Ciao and Bravo, Benelli, Ducati, Garelli, Sachs, Puch, and Peugeot.
This has no wires, they must be soldered in.
Normally used on Domino brand controls, but can also be directly attached to the handle bar with a separate mount.
CEV # 8193
