Just to be sure: how do you know you got an S2 and not an S2+?
The difference lies in the lenght and threads of the head (the S2 head is a bit longer) wherel:
the S2 has a long reflector and a short pill.
the S2+ has a short reflector and a long pill.
BTW: the black S2+ does NOT have a metal switch! Only some colored variants do.
