Hey guys! I need a bit of help with the right steps to wire my logictech mouse... which I modified. (removed buttons , re-soldered new pins and attached wire) However... there are 3 pins for each button, and 3 buttons in total as you can see from the picture. The extra button is under the LEFT click. My SPST momentary switch has 4 pins sticking out of it... I'm slightly confused as how to wire the "three wires" to this button. Seeing as the wires are probably, positive, negative and ground. However I don't know the order of the positive/negative on the switch... or on the mouse
. Ground can be shared but once again I'm not sure how to go about this.
Please help... I'm new at this. Thank youuu!
