Home Improvement Asked by Mat Kremke on September 25, 2020
I’m replacing an old timer switch to our closets and there is a blue, black and white wire attached to the old switch. Do I need a three way switch or do I get a normal switch and cap the blue off?
To me it looks like your switch requires a neutral; if your new switch is a snap switch (aka regular light switch) cap the white wire off. The black and blue don’t matter on a snap switch and can be on either brass screw; one is hot the other is the load.
