Why are you using an isolation pad under the transistors and what is it made of?2 transistors in parallel didnt work too well @ 2A 7V. Just get too hot one 60degC
What you show is just the part that sparks. If you look carefully they have a high voltage wire, like a spark plug wire but smaller in diameter connecting the sparker to a coil and circuit in the back of the stove. All of the burners and the oven use the same single coil and circuit to start the flames.Gas stoves/cooktops emit a burst of igniting sparks when the knob is pressed. Available at appliance parts stores in many flavors. No vibrator, no circuitries, simple self contained and low cost.
