Does It Matter Which Black Wire Go On Light Switch. If you wired it the other way around, hot black down and hot white up, you have a problem. Does the black wire go to l1 or l2?
I am trying to replace a 3wire light switch for a ceiling from www.justanswer.com
Just think 'white down, black up'. The black wire is the hot wire, it carries the electricity from the breaker panel into the switch or light source. If both wires are black but one has a white stripe, the striped wire is negative, while the plain black wire is positive.
Just Think ‘White Down, Black Up’.
With a switch loop yes, it should. If you wired it the other way around, hot black down and hot white up, you have a problem. If you wired it the other way around, hot black down and hot white up, you have a problem.
Properly You Should Have A Black Always Hot Wire Bringing Power In And A Red Wire Going To The Light.
Does it matter which wire goes where on a 3 way light switch? With a switch loop yes, it should. If both wires are black but one has a white stripe, the striped wire is negative, while the plain black wire is positive.
The White Wire Is The Neutral Wire, It Takes Any Unused Electricity And Current And Sends It Back To The Breaker Panel.
You may even see both red and black wires. Does it matter what wire goes where on a light switch? How do you wire a 12v toggle switch?

Just think 'white down, black up'. Just think ‘white down, black up’. It does not, as long as one of the wires is a “hot” that is to say a line voltage wire, and the other is a “switch leg” (wire going to the load) in this case a light switch.
If It’s A Single Pole Switch With Two Terminals, The Answer Is No.
The hot wire should come down from the ceiling on the white wire and go back up on the black wire. The other connection will be “load” where the load (ie light fixture) is wired. If your switch has a “line” marking, the always hot wire goes to this.
