    Hello,everybody.I want to ON an OFF a triac with a dc voltage using a
    simple push button to ON and OFF a 100W AC load like as a lamp.
    And I design a circuit for that;I attached my schematic
    here.
    Would you please tell me if it is correct or not?

    Thanks,

    What is the purpose of the potentiometer? If you just want to turn the lamp on and off I see no reason to have a pot in the circuit.

    Hello,crustchow.I used that pot [RP1] to set sensitivity of TRIAC.
    Also,I used R10 and C8 as a snubber.
    Would you please tell me for my purpose of to turn the lamp on and off
    with that push button,which components at my schematic can be omitted?

    Thanks,
