I'm replacing my bathroom switches (2) with a timer (for the fan) and a motion sensing switch (for the light) (lutron brand, not sure if that matters) and I ran into a very weird configuration:
So the fan switch was on the left of the image and had a ground wire and 2 black wires.
1 came from the wall and 1 came from the OTHER switch. The other switch (the light switch) had 1 black wire going into the back, and then another black wire (the one with part of the middle rubber lining taken off) going into the other one (they were both on the top portion of the switch, not sure if that matters)
Both switches only had "1" side with screws (So I guess single pole)
What is going on here exactly? There IS a GCFI outlet to the left of the switchplate.....is that maybe what the other black wire is for? If so.....what do I do with them? (Also does it matter at what position they are on the switch? IE: Top or bottom) since the right side bathroom light switch had them both on the top (one screw terminal and one push back one in the top)
