For a 4 way circuit to work, the three way switches have to be wired properly at the start and end of the path. Select the diagram that’s most like the scenario you’re in and see if you’re able to wire your switch! The switches might be arranged so they are in an identical orientation for off, and contrasting orientations for on. Most switches are standard but you might want to take out the switch and take it to the shop to make sure you have the precise replacement switch.
Whatever the case, the typical terminal is going to be distinguished from the travelers in some manner. It may be labeled and is usually a different color than the traveler terminals. The hot terminal on the receptacle is linked to the black wire running to SW2 where it’s joined to the frequent terminal.
The wire can’t rotate or wiggle. The wire connected to the light fixture hot lead or hot terminal might not be white. The red wire is linked to the exact terminal block containing the brown wire visiting the lampholder, the black wire is joined to the exact same terminal block that includes the blue wire visiting the lampholder and the earth wire is on the earth terminal. Usually, single conductor building wire in little sizes is solid wire, since the wiring isn’t required to be quite flexible.
