No.

SA shifters are quite different.

Incidentally, I know of at least three different types: the original
thumbshifters as found on a million shopping bikes, the iconic T-shift
on the original Raleigh Chopper and the far less iconic gripshift on the
new ersatz Chopper. Damn you, modern safety regulations!
