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, R75 for 75 ohms 2: “C” for outboard mountings or “Cin” for inboard mountings. 3: “B” for BNC 50 or 75 ohms, “T” for TNC 50 or 75 ohms or “R” for SMA (50 ohms only), F (75 ohms) connector types. |
4: “A” for 115 Vac, “D” for 28 Vdc or “H” for 12 Vdc. 5: “I” for indicators. 6: “L” for latching cutthroat. 7: “TL” for TTL Driver. |
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
