I'm trying to replace 2 dimmer switches with 2 regular switches, each dimmer switch controls 2 pot lights.
Each dimmer switch has 2 black wires as well as a green wire which seems to be ground but I'm not sure (the green wires both connect to each other with a bare copper wire, see pics).
I have the first switch replaced and working just fine with a 3 pole switch (green went to hole labelled COM and black wires went to each end). However when connecting the second switch in the same fashion the breaker trips immediately when turning it back on. What did I do wrong?
From what I can see, this is how it was wired before:
Switch 1 = S1, Switch 2 = S2
S1 "Off" side black is in a pigtail with S2 "On" side black (which has 2 wires from the wall connected to it as well).
S1 "On" side black goes into the wall.
S2 "Off" side black goes into the wall.
Greens are pigtailed together with bare copper.
This is how it's wired now with only S2 connected and working:
Green is going to COM.
Black that was on Off side is going to Off side.
Black that was on On side is going to On side.
Trying to do the same thing on the other switch as well trips the breaker.
