Switch half (99-1235)
A Lucas switch half (handlebar-mounted control switch component), no separate perch, PN 54033666.
This is a Lucas switch half, part number 54033666, the kind that clamps around the handlebar as part of a control switch assembly rather than sitting on its own perch. It shows up in the parts books under handlebar and control lever figures across catalog entries from 1971 through 1974, which puts it right where the switchgear lives on the bar near the levers.

The older reference number for this same part is 39596L, and the catalog record shows it was later superseded by 39595 - so if you're chasing this part under any of those three numbers, they all point back to the same physical piece.
Because this is a switch half rather than a complete switch, it's meant to pair with its mating half to form the full assembly on the bar. If you're not sure which side or which switch cluster you need, give us a call with what's on your bars now and we can sort out which half you're after.
