I'm trying to replace 3 light switches with new ones. Normally this is straight forward, but when I took the plate off, I was stumped. (Disclaimer: I'm not an electrician, I'm a recently divorced single woman who can't afford to hire one, and I'm just trying to do whatever I can to spruce up this old heap of a house I just bought.)
The left switch (L) is a single pole switch that used to control a ceiling fan, but now it controls a chandelier. There seems to be 2 wires connected to each screw on this one (one looped around the screw and one in the quickconnect hole). One of the wires comes off the switch on the right.
The center switch (C) is a 3 pole switch that controls two recessed lights. This one looks pretty straight forward.
The right switch (R) is a single pole switch that controls two recessed lights. One of the wires on this switch loops around and then continues on to the L switch, but I'm not sure why.
None of these old switches have a green ground screw. There are no white wires going to any of them. But when I look back in the box, there are lots of copper and white bundles. I can't tell where they go. Are any of these switches grounded?
I was gifted some Levitron 3 way switches and was told that even for the single pole switches, a 3 way can be used with no problem. I was able to replace C without any issue because it was a 3 way switch already, but it also didn't have multiple wires going to the same screw. But I can't figure out how to make L and R work. Also, the wiring I have seems too thick to use the quick connect holes in these new switches.
This house was built in 82 or 83, I think, but the original owner had some work done (converted garage to a room, then added another garage, etc). I have no idea if these 3 switches are original.
