Description
Dow-Key latching Lightweight Waveguide Switches are
superior to previous designs in terms of weight, size, and
current consumption. In addition, these switches are equipped
with Indicator Circuitry and with Transient Suppression
Diodes.
The total weight for the WR62 has been reduced by 46%
and by 55% for both WR75 and WR90 waveguide models.
The overall dimensions are slightly smaller when compared to
earlier Dow-Key designs and they draw 65% less current.
These waveguide switches are excellent for use in all types
of applications where size and weight are critical in such
as military and commercial airborne programs. For Space
Qualified requirements consult with factory for our Hi-Rel
Waveguide Switch product line, ranging in sizes from WR15
to WR112.
