To be honest, I'm just getting into electronics. I'm working for a lady and I found out a problem in her quarter machine, one of her leads was off on the positive side of the switch, so I bought a new one. Turns out it was counter clockwise.. So I had no option but to solder the old switch with a new lead. Am I able to test this with a multimeter? I put my multimeter to Ohms and tried to measure continuity and see if my soldering job worked. I see people glue their base of solder to help keep the solder stable and not go anywhere so I did that. What is I surrounded the solder with hot glue, is that why I am not getting any reading on my multimeter on Ohms? I feel my solder job was a huge fail. Is there a way I can test my switch and see if it works before I go out there?

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,... -
This is an ATX PSU rated for 550W powering 24/7 a computer load of about 200W, fed by a line-interactive 1500VA UPS. Mains is 230V.
- First issue: the PSU blew a mosfet on what I think is the active PFC boost converter, shorting its G D S pins together causing a short across the + and - lines produced by the rectifier on the 230V mains. The surge protector of the house tripped. When this happened I found that the UPS was unexpectedly disconnected from the wires of its battery. The UPS wasn't damaged, but I suspect this spontaneous detachment of a battery wire caused a condition that blew
