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 outstanding 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: STR7510D is a SP10T, 28 Vdc, Terminated, failsafe switch
