Mystery solved, yes that cap is on the mains cord side of the switch.

So what class of electric shock do you call that, high impedance , DC , of
little medical consequence in itself, but surprise effect could have
indirect consequences.

The IEC safety regs (60065) specify the maximum energy allowable for such
filtering caps. I forget the clause and I don't fancy looking it up right now.
