TL;DR - How do I re-wire this board to swap the button functions?
The whole story:
This is a bit of an odd question, and if there's a better forum (or even a more appropriate website) please let me know.
So, I work in an office that has a projector screen that retracts into the ceiling. On the wall there are switches that control the screen. This is very nitpicky of me, but whoever installed the switches managed to make it so that the up-arrow-button makes the screen go down, and the down-arrow-button makes the screen go up. To fix the problem, they just rotated the switch board 180-degrees so the arrows are pointing in the correct directions. BUT... in between the arrows is a button labeled "STOP". Because of the rotation of the switches, the stop button is now upside down.
I'd like to fix this problem somehow and I'm hoping someone can tell me how I can swap the up and down button functions, which will then allow me to rotate the switches 180-degrees back to their intended position so that the stop button will be right-side-up.
I'm thinking I just need to re-solder the wires in a different configuration? If so, how do I need to rearrange the wires?
I'm a complete noob to this sort of stuff, but I'm very interested in things like this and am willing to get a soldering iron and whatever other tools I may need to do the job.
Thanks in advance for any help you can provide!
