Lightweight Waveguide Switches WR62, WR75, WR90 WR62T1-4321 WR75T1-4321 WR90T1-4321 WR62T2-4321 WR75T2-4321 WR90T2-4321 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.
