A panel can have multiple ‘gangs’ on it, or a single dimmer with on/off, brighter and darker buttons.

A panel is simply put the control surface for your lights. Depending on what kind of switches you have right now, you’ll probably need a single or dual panel. Sometimes more. Single panels are square 86mm x 86mm, dual panels are wider 156mm x 86mm.

Pro tip: The switches will be identified by a label on the common terminal and/or the terminal screw will be a different color. So now you know your stuff about ways, gangs, panels and switches! Every house is a little different in how it’s wired and can differ in what you want and where you want it. But it’s really just about understanding what you want to do and what the terms are so you can find the exact product you need.

Manufacturers don’t really use the same naming for the way their products work which leads to a lot of confusion regarding ways, gangs, panels, and switches. We’re going to clear that up for you. We’ll also include images explaining some of these concepts that you can also find in the product description in our lighting store.

Pro tip: It’s likely you’ll also need to replace the existing switch box with a larger one to accommodate the extra wires for the 3 way switch. Connect the wires to the newly installed 3-way switches with ground screws using one of the two wiring diagrams (Fig. A or B). A switch is the control mechanism behind the panel. A switch can be 1, 2, or 3-gang. Alternatively, you can have a dimmer switch with on/off, brighter, and darker buttons. We don’t carry, and haven’t found, dimmer switches that are more than 1-way or 1-gang. The switch is also the part that you connect to your wiring. The switches we carry all require at least 3 wires, a L (Line), N (Neutral), and L1 (Load) wire.The Line wire is the wire that comes into the switch from your electrical box. It carries power to the switch. The L1 (L2, L3) wire(s) are the Load wires and carry power from the switch to the light.The Neutral wire completes the circuit and allows the switch itself to be powered. This is also why your lights have a Neutral wire but the wiring to your switch may be missing it. Older mechanical switches didn’t need a Neutral wire because that switch isn’t powered. If you need to bring a Neutral wire to your switch, this requires a bit of elbow grease and fish tape (aka wire snake).Now you know! There are two ways in the smart-switch world to have 2-way switches. One is the traditional way where both switches are wired to the light and each other. Another way has a primary and secondary switch only the primary switch is connected to the light and the secondary switch is wirelessly connected to the primary switch. I prefer the traditional way because it still functions even if your WiFi goes down but there are cases where the primary-secondary setup is useful, for example if you don’t have the control wire connecting the two switches.
