Most of the light switches have been set so to turn them on you have to push the top half and to turn them off you have to push the bottom half. These are 1 switch per light, (don't know the technical term), so it's not the case that another switch turned the light on, and a second switch is used to turn the light off.
I've always been used to pressing the bottom half of a switch to turn on, pressing the top half to turn off.
is there a standard? I can always learn to use the new switches"upside-down" but I have various other grievances with the electricians and am wondering if this is yet another example of their ineptitude/amateurishness....
thanks for all responses.
