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 isola-
tion. 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.
(2) “N”, “R” for SMA, “T” for TNC, or “B” for BNC 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
for 75 ohms SR75-T
