Standard Coaxial Switches
This RLC Electronics’ Standard 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-12.4 GHz. The package utilizes high density packaging techniques, hence the overall volume of the switch is less than 6 cubic inches.

To designate the switch desired use:
1: “M” for Manual, “R” for Remote, “R75” or “M75” for 75 ohms. 2: “in” for inboard mountings, if desired. 3: “B” for BNC (50 or 75 ohms), “T” for TNC(50 or 75 ohms), “N” (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-2-R-D-I is a remote operation, outboard mountings, SMA connectors, 28 Vdc; with indicators, failsafe operation switch 50 ohms. For 75 ohms SR75-2- – -.
