on/off Switch VU+ Uno 4k SE

[goral]

HI
Does anyone have any information on where I can buy the switch that is on the back of the VU+ Uno 4k SE?
I seem to have a problem with it as sometimes it won't turn on. Seemingly on, the white button on the front blinks slightly. But everything is dark.
After a few days of disconnection from the power supply, it worked again.
My conclusion is that the problem is with the switch - when I switch it on/off, you can feel that it is not fully on, there is no "click".
Thanks.

The switches are junk, I had the same issue with ultimo4k a few years back.

I worked out if you turn it off, then on and press the switch firmly and hold it, then it seems to work ok.

I do not touch the switch now, if I have to disconnect power, I either pull the power cable out, or turn off at the plug socket.
