We have lived in our house for over 20 years. We have a 3 light chandelier in our dining room. This evening I switched it on, there was a 'plink' and it went out ☹️ I said to DH 'oh, all the bulbs have gone'. And I SWITCHED IT OFF. As I switched it OFF all the lights came on. So the light switch is now in the exact opposite position to how it was. WTF???
For those in the know ((which is me as I have worked for more than 1 electrical contractor)) you can tell if a light switch is on or off by the position of the switch, years ago they used to have 'on' written on the top of the switch. So my switch used to have the protruding part at the top when it was on. It's now at the bottom.
AIBU to not get any sleep tonight in case the ghoulies return to play with my lights? 😱
