SPDT Waveguide Switches
These single pole, double throw waveguide switches are based on RLC Electronics’ highly reliable series of coaxial switches. A precision machined waveguide transition assembly is combined with coaxial switch technology to produce a compact device that features the low current and fast switching time of a coaxial switch with waveguide inputs and outputs. Units are available in various waveguide sizes covering 7.05 to 40 GHz with a variety of options.

Operating Power: 25deg C (Failsafe): 12vdc @ 575mA nom. (112, 90) 12vdc @ 250mA nom. (all others) 28vdc @ 200mA nom. (112, 90) 28vdc @ 140mA nom. (all others) (Latching): 12vdc @ 1 amp nom. (112, 90) 12vdc @ 120mA nom. (all others) 28vdc @ 430mA nom. (112, 90) 28vdc @ 60mA nom. (all others) |
Life: 1,000,000 operations Switching Time: 25mS (112, 90)Environmental Conditions: MIL-DTL-3928 Operating Mode: Manual, Failsafe, or Latching Switching Sequence: Break before make Maximum Hot Switching: 1 watt |
To designate the switch desired use:
1: “M” for Manual “R” for Remote 2: 112, 90, 75 etc for model number 3: “D” for 28vdc or “H” for 12vdc 4: “I” for indicators, if desired |
5: “L” for latching cutthroat, if desired 6: “TL” for TTL driver if desired 7: “Arc” for arc suppression diodes (N/A with TTL and Latching) |
Example: SRW75-H-TL is a remote, 12vdc, failsafe WR75 switch with a TTL driver
