If it's a plastic bodied Zadi switch, then it's pretty much disposable. If it's a metal body Zadi, then some of this may apply even though it's a Marelli switch. https://www.thisoldtractor.com/moto_guzzi_loopframe_ignition_switch_rebuild.html

From memory.. dangerous at my age.. all that holds it together are bent over tabs. As mentioned above..the *back* of the fuse block can be problematic, too. I think. It sucks getting old..  :laugh:

I pulled one apart to clean it. Went to put it back together and discovered the back could go on in multiple locations (most of them wrong). Mark everything as you disassemble or just buy a new one. I'm on third in 135,000 miles.

^^^^^ do this and it’ll be a lot easier. They used to sell just the contact base with a pigtail you could swap out and plug in but I lost the part numbers. Joe Eish used to get them because he tried to have any part that could stop you on a trip if it failed.
