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! 1 note concerning this test, if you’re working with a smart electronic switch or timer, this procedure is not going to work to check switch function.
Whatever the case, the usual 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 joined to the black wire running to SW2 where it’s joined to the frequent terminal.
Be certain the circuit is totally dead! If you think your circuit is wired correctly and the lights still don’t do the job, at least one of the switches might be defective. Confirm the circuit is wired correctly employing the subsequent guidelines.
Each sort of switch has a numerous symbol therefore do different outlets. To add over three locations for a single set of lights, you would just insert more 4-way switches between both 3-ways. 1 note relating to this procedure, if you’re handling a smart electronic switch or timer, the internal circuitry cannot be tested this way.
