I have 2 light switches (in one box) in my laundry room. The one switch is a 3 way which operates the light in my garage (just behind the laundry room). There is only 1 switch to the laundry room. I want to replace the switch to my laundry room with a sensor light switch as this is the entry from the garage and we always have to feel along the laundry room wall in the dark to find the switch.
When I pulled out the switches, it seems as though there is a hardwired wire connecting both switches. I assume this is used to get the power source to the single switch from the 3 way switch. However I don't know what to do to separate these. Please help!
