Difficult to describe but I have a lamp in the living room with 6 bulbs. When I was normal on the laptop one of these pears jumped (so only the glass in front of it) and the fuse has hewn out. I do the fuse again everything, in fact all the bulbs but I can't get the light anymore. Directly under the light switch is a socket in which I've plugged my laptop, monitor, small boxes and for a short time my phone. Can it be that something too much power ran through this box and therefore the light switch "can't work"? But why is only a pear of it burst the glass and otherwise it still works?
Only my biggest concern is, could happen even more if I leave the fuse on and the light just can't get out?
That sounds like a circuit break. Let this please check by an electrical company (costs borne by the landlord). Until then, can probably switch off only with the fuse again. The fuse flies, because the inrush current from the bulb is probably quite high.
I suspect that the bulbs are screwed vertically (with piston above). Since it can happen that the filament breaks, falls down and causes a lasting short circuit on the holding wires, so that the fuse triggers. The punctual heat at the short circuit in turn makes the glass burst.
The fuse protects the cable and has served its purpose. The light switch is however i.d.R. Designed to withstand a load of 10A. Since the short-circuit current but much higher and the fuse is not a panacea, the contacts will be burned in the switch and stick together. You can tell by the fact that the switch can no longer be locked in place with its typical click sound.
Turn off power, remove switches, insulate wires with terminals. Then you can turn the power back on and at least use the sockets. With the old switch as a pattern you can buy a suitable replacement in the specialized trade.
If that would have happened while switching on, then I would say, by the turn-on pulse hats cut the pear. This may happen in rare cases. The occurring short circuit then melted the switch together.
but if it happened so during the operation, this should not happen. But I can't completely rule it out.
Is it an electronic switch like a dimmer on the lamp?
