A little about the electrician.
Actually on our line filters, UPS, PSU there are switches that turn off the power to the connected devices. So, if there is a short circuit, overvoltage and other troubles with the network, will it harm the connected electronics being in the off position?I didn’t understand the pitch question
on the example of a lightning strike into the outlet
there are large filters and batteries that are equipped with such protection
there are small filters and stabilizers they are waxed, they are also protected from surges, but most likely in a smaller range
there is just a type of such an outlet for many devices with a switch there is just protection from mains interference when the current fluctuates slightly, etc. in fact, they are no longer needed because almost all devices are shielded in this way. when the function is off, any terminals there will most likely melt and all the heat work will be performed. when it is turned on, everything will melt and stick and a high current will slip further for a short time.
in the case of bp, everything is about the same. but I suspect that a good bp will simply burn out and everything else will be intact.
in the case of a short circuit to the device, they are in relative safety, because for them a drop in power occurs in parallel, the circuit is heated. and if the fuse is designed for a very high current, for example, there is not a fuse, but a thick bolt, all this will heat up to about the soldering temperature after which the circuit will break. for a device on a network, this means that its plug will get very hot if it is in a circuit with a short circuit.
in the case of a drop in power, everything is the same only without heating. the computer will work harder and the ultra good unit can still pull it out for a little more than 100 volts and then it will turn off. a very bad unit will burn out from overvoltage. especially if it is some kind of 400 watt no-name of many years ago and the power pitch is packed into it to its limit.

Just wondering. Should I leave the equipment connected to the surge protector, but leave the switch in the off position? Or still pull it out of the socket.
I pull it out simply because everything on the line with the pitches eats a lot of energy in idle time. and turn off the click so it will break in a few years.
