Background information
Botswana, as a former British colony, adopted the pre-1950s UK standard: types D & M. Originally, there were four plug and socket versions: 2 A, 5 A (=type D), 15 A (=type M) and 30 A. Botswana initially standardized on both the 5 amperes plug (type D) and the 15 amperes plug (type M), but in the end only type M remained.
Appliances with C-plugs are commonly found and are used with adapters. Occasionally, you may come across a South African double socket that has both types M and N.
