Yes & no.
Those three switches control lights in three different places and use 3 different breakers as I discovered.
I had no idea she wanted me to do the switch swap so I had no tools or testers with me. She said the circuit breaker was off but I verified it before I touched it. Sparks! Turn off more breakers, no more sparks with the screw driver test.
I sometimes think I should just pack a tool box for MIL trips. I have done everything from replace toilets to hang ceiling fans in a room with no electricity in the area. The insulation in her attic is over two feet deep. Ask how I know!
