Is this dangerous?

[BecksBristol]

I have got into the habit of disinfecting the light switch next to my front door with a Dettol wipe. (It's pitch black in the entranceway until the light is switched on, sothere's no chance to wash my hands first.)

Today I was disinfecting it when I got an electric shock in my fingers! It definitely wasn't static—it felt like a more mild version of what you get when you touch an electric cattle fence.

And now, although the swich is off, the light is still on, in a dimmed state.

AIBU To think this is dangerous and I need to call an emergency electrician? Or should I just leave it to dry and see what happens first.

@DynamoKev Thank you for your advice. Actually it is a two-way switch. There is one at the entranceway (this is the one that gave me a shock and was changed) and a second one at the other end of the corridor.

Should the second switch be changed also?

No you don't - changing a single switch is within the realm of a competent DIYer

It's within the capabilities of an incompetent one, too - I put in dimmer switches in my old house, armed only with my Collins DIY manual and a screwdriver!

And I am woefully useless at anything practical.

It needs a serious looking at

You can't ever wipe a light switch with a slightly damp cloth?

The point was you can't get a one way switch wiring wrong as there are only two wires and it doesn't matter which way round they go - for a two way you'd need to phot the wires first and then replicate the connections on the new switch, that's all.

No need to change the other switch.

Mains power and water don't mix - switches aren't insulated, but it depends on your definition of "slightly".
