A round terminal type boasts wide varieties and high mounting efficiency.
Supplied with radial taping.
A round terminal is most suitable for radial auto-insertion/
mounting on the PC board.（Able to reduce switch rising
when mounted, to reduce cutter wearing of the assembly
machines.）
Better solderability thanks to no rupture plane of the
