Not having much else to do this morning i decided to connect up my new linestage on my dac and swap out the spst switch for a double pole one. It was a fairly simple job and I really should have been paying attention, however, when I was putting it back together I forgot about the heatshrink on the new switch and shocked myself on the terminals. I took it as a clue that I shouldn't have been talking while sorting out mains voltages. I have never shocked myself before with that voltage building a variety of projects and came as quite a surprise.
So, anyone else out there who reads this, take it as a reminder that shocks from mains electricity are dangerous and hurt like hell! Take precautions people! I was foolish enough to be doing two things at once and it could have been far worse.
Safe working people!
