Re: 3com Officeconnect 8port switch
replaced with what panasonic FC i had
1500uf 10v (0.03 ohm)
1000uf 50v (0.03 ohm)
these switches take 10-30v dc. power pack for this switch is actually 14v. but the 8 port hubs have a 24v power pack. The large cap could therefore be a 16v if the power supply is only 14v. but to keep to the correct spec written on the outside 35v+ is the correct value and useful anyway if you wished to swap the power pack from a hub to the switch in future if the switches power supply failed.
alternative hole clearer
works fine, no hissing now. actually these units seem to work fine even with badcaps. you can find them in small offices all over. a nice buy on the secondhand market as they have no fans inside and the wall wart power supplies seem to last for years.Attached FilesLast edited by willawake; 04-03-2006, 08:02 AM.Comment

3COM OfficeConnect Gigabit Switch 16 (3C1671600)
The switch has served me for 10+ years (was new when I bought it). It's a nice switch with connections on the back which makes for quite a clean desk. Reason for taking it apart was that the cooling fan was noisy so I expected it to be dirty/dusty inside and the need to order a new fan. What I found was that it was very dirty/dusty and some electrolytic capacitors which needs attention. There are 3 capacitors which needs to be replaced but the ESR on some of the other ones might be bad as well so I think I'll replace them all. Original... -

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... -
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 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,...
