Rohde & Schwarz SMIQ/SMT/SME Signal Generator Compatible Power Button

thingiverse

A replacement front panel power button designed for the Rohde & Schwarz SMIQ Vector Signal Generator, compatible with several other instruments thanks to R&S's shared design elements. It should fit seamlessly into various series, including the SMT and SME signal generators, as well as potentially many others of similar vintage such as the FSEA/FSEA spectrum analyzers, the FSIQ signal analyzer, and even the ZVR/ZVRE network analyzers. Although I have not removed a button from any of these instruments to verify its compatibility, at least in the case of the FSEA and ZVRE models, the button dimensions appear identical, but the switch behind it feels distinctly different (soft power switch vs. main line input switch on the SMIQ), leaving me uncertain whether the rear hole matches the switch used. This replacement button accepts a 3.4mm square switch stem and features a press fit that is slightly tighter than the original part, which relies on a drop of glue for secure attachment.
