Two switches in one case! The B5-7 series basic switches are
miniature in size but feature up to 10 amps switching capability
of 100,000 cycles.
The molded housing is rugged and structurally stable. The
terminals are sealed against solder flux entering the switch and
are bright acid tin plate brass for excellent solderability. B5-71
has end terminals; B5-72 has front terminals.
