Used in Balanced AC systems where it shorts to ground by default, so you open it to cause power to flow to the light. Thank you CM1 but I'm still unsure leaning towards shutter type is that correct?

Dang it CM1 but I still think you are partially correct seems like it's a normally closed switch and you have to move it to open if that's correct. Much appreciated I'm still confused slightly on the nomenclature but confident I need a shutter for replacement.

Yeah, I think of it in non-Vespa terms (Normally Open & Normally Closed), and then get backwards in my head on the whole "opener" or "shutter" thing.

Also, much like a clutch castle nut, the only time I'd ever encounter a shutter switch would be when I ripped it out along with the Balanced AC system it came with.

It is backwards : Normal is with the pedal pressed.
