Triacs come in a wide variety of packages. All have three terminals: MT1, MT2, GATE, and a built-in heat sink. Before screwing it anywhere, read the documentation! The radiator can be internally connected to one of the terminals. In that case, you must treat it as if it was under high voltage. Ver mais Even though current can flow in both directions via the MT1 and MT2 terminals, they are not interchangeable. To properly trigger the Triac, you … Ver mais I will present you two versions of the schematics depending on your needs. You can use the simple or the more sophisticated version.
