1)There is some static harm to the electrical
parts from colophony in the washing machine
or humans. So it is better to eliminate the
potential static by grounding the humans or
touching the plugs.
2)The rated voltage of the SCR in PCB is
220-240V, so it's possible to be electrical
shock. Please take care while strong and
