Hi to all, a few days I received NanoNVA-F. I bought on Aliexpress. Unfortunately, the rotary switch only worked one way and blocked the functions on the touch screen. I had to undress it but repair is impossible. Does anyone know what type of this switch is and where to buy it? The seller has not yet responded to my complaint. Happy New Year Slawomir
Slawomir, BH5HNU, the developer of the NanoVNA-F, is generally responsive to hardware issues when you bring them to his attention at /g/nanovna-f/messages . You might leave a message for him at the above link and see if he offers any remedies before attempting any repairs.
had the same issue with mine,the flimsy legs snapped off my jogwheel,managed to dremell away the plastic put 3 blobs of solder on the remains of the legs then sweated it back on the pcb,good idea but a crap quality switch!
This is the weakest element of this device. It has not worked since the beginning. I have 3 weeks. I need information about the type of this switch and where to buy it. I will order 2 pieces.
Same problem here. I purchased two from eBay seller harborcityelectronics, see item # 121096249091. Repair was straightforward with no issues and I have a spare.

Hi all,talking of the jog switch,im thinking of fitting buttons to mine,just wondered is the common pin the center leg,looking from the rear ond the top left pin the enter connection?,thanks in advance.
To anybody who is wondering how the switch works internally, mine was broken, so I tore it apart and photographed it. Then I enhanced the photo to explain the contacts.
