FMH-3 Microphone will not PTT

in SmartSDR for Maestro and M models

The FHM-3 microphone stopped working during a QSO. There was no PTT closure.

I opened up the mic and found the PTT microswitch is stuck in the Open condition and will not Close. No click to be heard. I removed the PCB and Ohmed out the three pins on the back of the board (see photo) and there is never a switch closure.

The microswitch is broken. Is there a source for a replacement microswitch? The switch is not marked. A maker's mark or a seller on-line?

Thank you.

I tried to post a photo (.jpg) and this site will not allow it.

    hi Rob(?)… when this happened to me, I contacted the sales department @ Flex via email, and they were able to sell me another FHM-3 at very reasonable cost.

    Mine broke after about 10 minutes of use.

    I replaced the switch with a TE Connectivity SAJ405XHL0N30SDTLRQ

    Digikey has stock.
