Just gone to turn the lights off in my living room, and at the same time turn on the upstairs landing lights - you can touch both easily.
I felt a 'tingle' when doing the above, but only when touching the retaining screw of the living room lights (the only exposed metal on this switch, back box is earthed) and the front plate of the landing light (metal front plate and earthed back box)
Not a proper belt, more a tickle really, and nothing to cause any hurt.
The measurement was made with a Fluke 83 DMM. The voltage does disappear if I drop a low-impedance load across the two earths (incandescent bulb on a lead)
I'm more an electronics guy rather than electrical.
I was wondering what would cause this voltage (with no apparent current behind it) and if it's something I need to have sorted out?
