Switchcraft Littel Plugs all feature
one-piece tip rods for added strength
and durability. All are offered in a
wide variety of configurations,
including straight, right angle, shielded,
screw or solder terminals. The
Heavy Duty Speaker plugs have
larger cable clamps and are rated at
15A. The Silent plugs have a unique
circuit-closing device which stops
hums, pops, and squeals when the
plug is removed or inserted from
the jack. Miti plugs feature heavy
duty brass construction, rugged
cable clamps, and spring flex reliefs.
All plugs meet EIA standards for tip
configuration, which ensures you
they mate properly with the jack.
