AMEN to that, Ken!  I have had the Johnson TR switch hooked up at my 
"happy days" setup
for the last 40 years, and it will still give a good burn if 
touched.  I am surprised that
it has remained intact all these years without burning up!  (I don't 
think I will be
figuring out the electric costs to generate that heat for 40 years.. 
I don't need any
more negative thoughts today) :-)
