Miniature Coaxial Switches
This RLC Electronics' Miniature Coaxial Switch is a single
pole, two position type. The switch provides extremely high
reliability, long life and excellent electrical performance
characteristics over the frequency range of DC-65 GHz.
The miniature package utilizes high density packaging tech-
niques, hence the overall volume of the switch is less than 3/4
cubic inch.

To designate the switch desired use:
(1) “M” for Manual, “R” for Remote.
(2) “Min” for outboard mountings or “Minin”
for inboard mountings.40 GHz is inboard only.
(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) “26” for 26.5 GHz option., “40” for 40 GHz option,
“50” for 50 GHz option, “65” for 65 GHz option
(8) “Arc” for Arc Suppression diodes (N/A with TTL
and Latching)
Example: SR-2 MIN-D is a remote, outboard mounting, 28 Vdc; Failsafe switch, for DC to 18 GHz use.
