I have an idea for an electric portable ciagarette lighter.
the idea is using an heating element connected to a switch and battery.. I have struck an issue however and its to do with temperature.
I was trying to make it safe and then realised this could get quite hot so I was wondering if there was something like on a fuel bowser pump (when it gets full the handles clicks and it doesnt over flow) but for heat?
or is there a very small circuit that will totally disable the power until you release then reapply pressure to the switch. I am trying to make it small
