When sparked by PSCN, will be active for a certain amount of time (use heat to set time, every 100°C would be a second - when the temp of one particle of this switch is heated, all particles of the same type touching it will be brought to the same temp). When active the switch will conduct electricity.
Another idea:
Channels should be able to go in the negative temp for channels. Currently only -20 and -100 channel works. At -200, it acts like -100.
Gasoline (GSLN) burns faster and hotter than oil, made by cooling/pressurising oil. Ethenol (ETHL) made by pessurising plant, burns slightly less than GSLN but releases almost no smoke
I am in favor of a form of thecreatorgod's idea, i realize this would crash the game, however i only see the need for three new particles: a particle like DMND but not conductive to heat a particle sensor in particle form and an E-wall in particle form (i dont think INVS is close enough, because making non-continuous pressure requires e-walls) i realize this still could slow down the game, i am not a coder, but it is just a suggestion.
When I say timer, I am referring to the time before the switch will automatically shut off. Yes, water can be used to turn it back off, but that takes space. Having the switch with an eternal timer would save quite a bit of room.
please make plastic it burns at high temperature and melt, do the concrete, it is not heated and does not burn, make the laser make the paper (it burns very quickly, If wet it turns into a tree can be used as a vehicle fire (for which some machines)
