If that's all you want it's easy.   The way most automatic heaters are
constructed, all you need to do is open the tube they are in, put a wire
across the two terminals of the heater element, put them back in the tube,
cut off the plug, and use the result as a switch.  Be sure to use a big
enough heater tho, so it has heavy enough contacts to carry the wattage of
your diy cable.
