Lightweight Waveguide Switches WR-62, WR-75, WR-90, WR-112 WR62T1-4321 WR75T1-4321 WR90T1-4321 WR112T1-4321 WR62T2-4321 WR75T2-4321 WR90T2-4321 WR112T2-4321 Description Dow-Key's 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 WR-62 has been reduced by 49% and by 52% for both WR-75 and WR-90 waveguide models, which corresponds to 300 grams for each model. The weight for WR-112 has been reduced by 53% which is equivalent to 500 grams. The overall dimensions are slightly smaller when compared to earlier Dow-Key designs and they draw now 65% less current corresponding to 350 mA . Hence, this series of waveguide switches consumes less power. These transfer waveguide switches are excellent for use in applications where size and weight are critical in such as military and commercial airborne programs.
