Switchcraft introduces a new series of 2.5mm jacks.
These low profile jacks come in a wide variety of circuits,
both 2 and 3 conductor versions. Circuits include mono
closed, stereo open, stereo tip closed and ring open, and
stereo closed. The MDSMT Series is available on tape
and reel only. Contact Switchcraft for exact dimensions

tronic equipment that features remote speakers, head-
