NVR switch removal

[Gragson]

Femi bandsaw NVR is playing up not latching on more often than not. So looking to replace.
Is there a trick I'm missing in getting the switch out of the case?

Tried pressing in the white tags either end to push out but the wont go past the case enclosure, do they swing out some way?
Don't want to force and break the switch enclosure.

Also, I'm guessing these style NVR switches are not repairable or worth it?
Are they all much of a muchness or better than the usual eBay offerings?

There is one place in China that makes all of those switches. KEDU is the manufacturer

Well I got it out by warming up the whole thing carefully with hot air and a flat blade bradle, those sprung plastic lock tabs were not shifting prior.



Question remains on a replacement, are they all much the same?

Yes, they are all the same. I've bought several from AliExpress and never had a problem.

The 4 pin ones are easiest to wire.

Cheers I've ordered a couple, looking around I didn't realise I had so much kit with these.
The Femi packing up when I needed it put me out, so sods law means I will never need the spare for any of the other stuff (or be able to find where I have stored it) But it most likely will!
