I have been manually doing the plugging and unplugging for so long, just dont want to do it anymore. What do you mean the wire is still connected when the switch is in off postion?
Isnt avr and ups giving the same protection except ups got battery? Nowadays lightning strikes multiple times within 1 minutes, what kind of avr or ups can prevent that?
Previously using apc ups, gone through 3 of them for my pc, all bye bye now(they didnt get strike by lightning cause I was quick enough to unplug the power cable. Now havent decide what ups to buy for my pc yet. It seem ups breakdown mostly within a year, at the most 2 years max. I use ups mostly to enable me to save whatever data when there's power failure. Didnt dare to try let it switch on and connected during lightning strikes to see whether it survive or not.
I dont know the exact mechanism used in those box, but these switches needs physical wires to be connected at-all-times (refer picture below).
So when lightning strikes, it will probably still pass-thru the wiring and still overload your hardwares.
Get what i mean?

How is this better or worse than cal lab lightning isolator?
Never tried it before, this AVR has built-in fuse.
When lightning strikes it will blow the fuse and just replace the fuse.
