    NEC TurboExpress On/Off Power Switch Replacement Help

    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. I initially searched for "NEC TurboExpress power switch" and didn't come up with anything, so then I started looking for a generic replacement from Mouser or DigiKey, but the options are so vast and there are tons of different types like SPST, DPST, etc.

    This switch only has an ON or OFF position. The switch uses 10 pins total, with the 6 "middle" pins being the ON/OFF and the leftover 4 on each "corner" are just ground for the shield that goes around it. Through-hole and right-angled.

    Here are some photos of what I am working with. I'm hoping someone can help me figure out which replacement switch I can use to get this thing turning on/off again. If you need any additional info or need me to measure something, I will be glad to do so.

    Thanks.

          I have, but what is confusing me is the circuit type DPST, SPST, etc. Not sure which one I'm supposed to be using

                  Just wanted to come back and update this. I purchased the following switch from eBay: https://www.ebay.com/itm/275901936717 and it worked. I did have to modify the pins a bit to get it to fit, but it works. Just updated for anyone else who might read this in the future. Thanks!

                      Netgear JGS516PE Switch Fan Replacement
                      by shovenose
                      I got a free Netgear JGS516PE PoE switch and it works fine but the fan makes a grinding sound.

                      It uses a 12V 3 pin fan with a non standard pin out. So I took a Noctua fan and moved the wires around in the connector to make it work.

                      Unfortunately, the fan spins for just a couple seconds before it turns off and the Fan Fault LED comes on.

                      I think it's stupid they designed it to stop powering the fan when it detects a fault but I guess that's what they chose to do.

                      Instead of spending $30 on the correct replacement fan, does anyone have a clean...

                      Replacement LED switch for Powercolor Hellhound
                      by Travis Thomas
                      Hey all,

                      So I bought a second hand Powercolor Hellhound Spectral white 6700 XT a while back. The only problem with it is that the LED switch on the PCB is broken. Anyone have a PN I can use to solder in a a replacement? Also, a Boardview or schematic would be good too. Thanks

                      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...

                      Kenmore electric range replacement infinity switch?
                      by CapLeaker
                      Actually this range had multiple problems but I fixed all the others already.

                      I am stuck finding a replacement infinity dual burner switch for a Kenmore C970-605121. The dual burner is stuck full on as soon as you turn the knob either side, either the difference of either only one or both burners running full tilt.
                      I tried cleaning it inside contacts, but that didn’t do anything.

                      I believe the dual burner switch reads a part number of: 318191021 which is hard to find. I came across a 318191026 part number but it has 2 pins on the row missing. Is there anything...
