Hi Dominick,

I have an old rotary dimmer switch that I want to replace with a newer and similar switch. My father had tried to do it some years ago but he wasn’t used to 3 way applications. I tell you this because in his attempt he did something strange to the circuit when he put the old dimmer switch right back where it was: the other non-dimmer switch, which he did not work on, has since only been functional when the dimmer switch has been left in the pushed-on position. The non-dimmer used to work fine on its own before this. I have included some pictures of the current dimmer connections, and ask you to consider that something is not right with these connections. Also, I am wondering how to connect my new dimmer. It has a green wire, 2 black wires, and a red wire. I don’t know where to attach them.

Thank you!
