Standard Transfer Coaxial Switches
This RLC Electronics’ Standard Transfer Switch line provides extremely high reliability, long life and excellent electrical performance, it features extremely low insertion loss and VSWR over the entire DC-12.4 GHz range while maintaining high isolation. On remote latching units a manual override option allows the user to switch manually without power applied.

To designate the switch desired use:
1: “M” for Manual, “R” for Remote, R75 for 75 Ohms. 2: “N” (50 or 75 Ohms), “R” for SMA, “T” (50 or 75 Ohms) for TNC, or “B” (50 or 75 Ohms) for BNC or “F” type connectors 3: “A” for 115 Vac, “D” for 28 Vdc or “H” for 12 Vdc. |
4: “I” for indicators if desired. 5: “L” for latching cutthroat if desired 6: “TL” for TTL Driver if desired 7: “O” for Manual Override. |
Example: SR-T-N-D-I-L is a remote, Type “N”, 28 Vdc; with indicators, latching cut throat switch. 50 ohms
