Why is my new light switch not working?
If the light switch isn’t working at all, there may be no power to the circuit. Make sure the breaker to the switch is on in your breaker box and determine whether there are any other tripped outlets and switch them on as well. This is the simplest solution you’ll want to try first that may fix the issue.

How do you know if a light switch is wired wrong?
If either wire at the light fixture is still hot then the switch is wired incorrectly. If one of the wires is still hot at the light fixture with the switch in the off position, then you most likely have the light switch on the neutral wire.
What happens if I don’t ground a light switch?
So there you have it, your home may opt for screws, cables, or grounded boxes, but your switches should all have a ground outlet to ensure your safety is secured. Without it, you put your body at risk of completing a circuit holding lethal electrical charges.

Why does my light switch have 2 black wires?
STEP 3: Identify the terminal and ground wires. Observe the layout of the wires. You should see two black wires, each connecting to a different screw on the side of the switch. These are called terminal screws. You will also see two white (neutral) wires that connect to one another in the box.
Does it matter which wire on a light switch?
It doesn’t matter as long as you do it the same on both switches. So, if you connect it to the upper right terminal on one switch, connect it to the upper right terminal on the other switch. Connect the second traveler wire to the terminal opposite the red wire terminal.
What happens if you wire live and neutral wrong?
Simple answer: it creates a shock hazard/unsafe condition.
Do electrical switches go bad?
Like any other thing in the world, they break down over time. Every light switch, at some point, will go bad. But they’re a simple device that doesn’t have a lot of moving parts so they’re built to last and don’t break down often.
Does positive and negative matter on a light switch?
The circuit works the same no matter where you put the switch. Part of the electrical code (for house wiring) says that the switch should always go between the hot conductor and the load. This is for safety.
