    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.
            Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

              I think I will replace the whole extender,is this one any good?

              This is the current one:

                  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.

                      Wait,how many watts is limited per socket on the extender,with this cyberpower model?
                      I'm confused now.

                        Re: sparklling and buzzing around the switch on the extender cable

                        You can pull up to 10A total through the power strip using any combination of loads on any sockets.
                        Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

                            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

                                    I ordered the APC one and should come tomorrow.
                                    I guess if issue persist then I have some wall socket issues,God knows what...

                                      Micro Momentary Push Switch?
                                      by Natob82
                                      Great to be here! I'm a newbie here trying to find a "micro", momentary push switch to repair a Sony "clamshell" video walkman. This micro switch has long since discontinued by Sony, however I hope there are third-party switches of the same size and functionality that I might be able to source to play the same role. The purpose of this switch is to tell the video walkman that the user has activated the mechanical tape eject button, turning that physical action into an electronic signal that tells the tape transport mechanism to open so one can load or eject a video tape. I...

                                      NEC TurboExpress On/Off Power Switch Replacement Help
                                      by grimacelord
                                      Hello,

                                      I've been working on a NEC TurboExpress and I accidentally got the plastic inside the power ON/OFF switch too hot while doing other repairs and melted it. At first, it would still power on when sliding the switch, but you had to really press inward while sliding to get it to work.

                                      I removed the switch component and tried to gently melt the plastic back so it would work more reliably and all I managed to do was make it worse.

                                      I need to find a replacement On/OFF switch for this, but having some trouble figuring out which kind of switch I need....

                                      Help making a switch work the opposite way with a relay
                                      by SluggerB
                                      I have a very small float switch, I'm using in a very small tank. It only fits in one way. Link https://www.amazon.com/uxcell-Switch.../dp/B07DZ1J2GB

                                      I want the switch to be open when the water is high, and closed when the water is low. Unfortunately it works the opposite. And since this switch is designed to be underwater, it's all sealed up, there is no taking it apart or hacking it up.

                                      It will be driving a water pump, basic idea, when the water is low, switch closes, which turns on water pump, when enough water is in the tank, float switch floats,...
