No, he's right. ALL mechanical switches will spark. Even
mercury switches. It's not visible as a rule, but unless the
voltage is at the zero point or close, there is a spark
generated. It's the nature of electricity. That's why you don't
want ot turn lights on or off in a room discovered to be full of
gas.
