I was changing the light switches around the house when I came upon this setup.
The two switches to the right are all wired using the hot wire (black) from the two electrical wire on the back panel. All cold wire (white) are tied together and are left unused.
I am no expert and not even an amateur, but I find this setup strange.
If I change the light switches, should I follow the same connection setup in the picture or try using a standard black-white setup?
The switch on the left (not visible) is a three-way switch.
