Do you mean "I want only a pushbutton" or "Is the slide switch what you hit to make it vape?" the "diagram"
I posted is for main power on/off slide switch PLUS pushbutton vape-activation. If you don't care about the slide switch, just bypass it in the diagram, and wire the negative wire from the negative terminal through the push button.
okay, one last question...what if I don't want to use the slide switch and I just want a push button activation?
