Yesterday in Metalwork we soldered wires to switches, which will allow us to toggle on/off a fan that'll push a car forward. But today one of the wires broke off the switch, and I'm not sure if there's any point in trying to put it back on. Here's a picture of the part of the switch the wire was connected to, with the red box around it.
It's probably hard to see, but there is already a lot of solder on the joint from before the wire broke off, and I want to know if it's possible to get the wire back on. Soldering to one of the other joints isn't an option - I tried and nothing happens to the fan.
