In other words, a 3 way switch is made up of one light that’s controlled by two separate switches. The most important rationale is that there are several ways that a three way switch can be wired. Wiring a 3 way switch isn’t that difficult. The answer to how it works, is to have an extra hot wire that runs between the two switch boxes. Before you begin wiring 3 way switches, you must understand this in order for you to have a three-way circuit you should have three-way switches.
Finding three way switches to purchase isn’t hard in any way. Installing a 3 way where you didn’t have one previously is another issue entirely. There are a lot of ways they may be used and wired.
Understanding three way switches can be problematic for a novice. The switches might be arranged so they are in exactly the same orientation for off, and contrasting orientations for on. To do this, it must be capable of operating two different circuits. Decide on the diagram that’s most like the scenario you’re in and see if you’re able to wire your switch! It’s as long as you comply with the schematic that is supplied with the switch. 1 note relating to this test, if you’re managing a smart electronic switch or timer, this procedure isn’t going to work to check switch function.
