See also my previous question:
Where I made a circuit directly by mains, and as proposal by very useful comments to use a separate 'control' circuit at 9 or 12V.
However, according to this video:
the switch under the 'plateau' is directly connected to 220V.
However, in my case I want to make a very important change: I don't want to use plexi glass, but a metal grid (like this):
I assume it would not safe to make a switch directly under this iron grid that is connected to 220V? Or is it actually not really safe for the plexi glass solution as in the YouTube video neither?
(Btw, I think according to the related earlier question, I'm going for a transistor/relay/triac solution anyway).
And a side question: another band I seen, uses a foot switch instead of a switch under the grid. I'm almost sure that foot switch is connected directly to mains (meaning 220V goes through it). Now this is seen quite often with living room lamps etc... but I wonder if this is safe on a music stage (what if someone would drop beer over it, and the foot switch is not 100% 'closed' somehow) ?
