Type C Coaxial Switches
This RLC Electronics' Mid-Size Coaxial Switch is a single pole,
two position type providing extremely high reliability, long life
and excellent electrical performance characteristics over the
frequency range of DC-18.0 GHz. The package utilizes high
density packaging techniques, hence the overall volume of
the switch is less than 3 cubic inches.

To designate the switch desired use:
(1) “M” for Manual, “R” for Remote.
(2) “C” for outboard mountings or “Cin” for inboard mountings.
(3) “B” for BNC, “T” for TNC or “R” for SMA connector types
(4) “A” for 115 Vac, “D” for 28 Vdc or “H” for 12 Vdc.
(5) “I” for indicators if desired.
(6) “L” for latching cutthroat if desired.
(7) “TL” for TTL Driver if desired
Example: SR-2C-R-D is a remote, outboard mounting, SMA Connectors, 28 Vdc; without indicators,
Failsafe switch 50 ohms for 75 ohms SR75-2C
