Default sparklling and buzzing around the switch on the extender cable

My dear electronics repair guys:
I switched off this thing (on picture) via switch and switched back ON but immediately I could hear buzz and like a little electric shock around red switch and these 2 lights started to blink but should be ON all the time.
I then switched it OFF,got afraid that I burnt the PCs via electric shock.
I saw a little current flash around this red switch and I could hear buzzing.
All the devices were connected to the extender when I did that but none of them were working at that time (they were in standby mode)-
This is second time it is hapening.
What is this issue and why does it happen?
I hooked up all the devices to it,but mostly only 3 work at same time (5.1 system,router and one PC,never more)
This device is from some Konig brand,not very cheap but not expensive too.
I think when all cables are disconnected and this Konig device is ON I can plug in each device,no issues,no flashes,but I got flash when I flip the switch ON and all devices are connected to this Konig extender.
Is this dangerous for my PCs?
Do I need to purchase second extender?

This one wasn't used that much (Dad told me he purchased it new few years ago) and the scars on the back are probably from touching the floor.
The same thing happens when I connect any laptop charger to second extender,I get lightning flash and a buzz.This only happens with laptop chargers on second extender.

Those switches are crap they do not last if you are switching it off and on from the extender just change the switch to a 15 amp one if you can find one

Or do away with the switch on the extender and use a wall switch inline on the power supply cable to the extender which is what I would do if I were repairing this device

if you replace the switch then get an illuminated one - you can never have too many lights!
and get green rather than red - for some reason the lamps last much longer.

all extenders here come with same switch all all are made in China.
Could it be that I have some electrical issues in my room because same issue happens with another extender connected to wall socket just above this one.
Maybe there is some issue with ground in wall socket,huh?
Is this what is called "inrush current"?

Crappy switch that's failed. Just replace it.

U mean 275 W per socket?
But afaik PC takes around 400 W of power.
I don't understand it's 10A*220V=2200W.
My whole system when would be ON (all 3 PCs+5.1 system+monitor+router) doesn't use that much power.

that's total load and you know it

10A is the rating of the plug and cable.

You can pull up to 10A total through the power strip using any combination of loads on any sockets.

I believe the Cyberpower is rated 10A total - from all eight outlets, as a maximum.
But it's made in china so derate by 50% lol. Just kidding.

I think you could pull 5A from one outlet, leaving 5A for the the other 7 outlets.

Even if were all the devices powered on I caclculated that total ppower consumption wouldn't exceed 1.5kW.
So the extender is not the issue (my opinion).
Something other is happening here.
Average modern PC won't exceed 500W of power consumption.
Could it be the issue that on one of the PCs I have installed 1200W PSU which ofc doesn't use 1/3 of it's power.

The problem is that the cheap Chinese power switch has worn out and failed. Replace or bypass the switch.

Okay.I purchased yesterday new switch 15 A.
The issue is that all extenders share the same type of switch.
Will picture the switch later
