75 OHM Terminated Multi-Position
Coaxial Switches
(3 to 10 Position)
RLC Electronics’ 75 ohm, Terminated, 3-10 Multi-Position
Coaxial Switch line provides proven reliability, long life and out-
standing electrical performance. These switches offer electrical
characteristics featuring extremely low insertion loss and high
isolation over the entire DC-2 GHz range and are useable
beyond 2.5 GHz. These switches are available in remote failsafe
or latching operation. Standard RF power rating is 1 watt cw
limited by the termination.

To designate the switch desired use:
(1) ‘3’ thru ‘10’ for number of positions
(2) ‘H’ for 12 Vdc or ‘D’ for 28 Vdc
(3) ‘I’ for indicators if desired
(4) ‘L’ for latching cutthroat if desired
(5) ‘TL’ for TTL Driver if desired
Example: STR75–10–D is a SP–10T, 28 Vdc, Terminated, failsafe switch
