How does a 2 way toggle switch work?
They typically have two terminals. One is for input, the other for output. In one position the switch is 'Open' and no connection is made, and no power can flow to the accessory. In the other position the two terminals are connected and power can flow through.
It is perfectly legal to wire a light switch without the inclusion of a ground. Dimmers will require a ground wire but traditional toggle-type switches will not. Omitting a ground wire on any switch is not recommended.
Wiring a 2 Prong Plug
The side of the cord with the ridges is connected to the wider prong with the silver screw. The smooth side of the cord is connected to the narrower prong with the gold screw. Wrap the wire around the screw and tighten the screw. Close the cover and tighten the screws.
Switches don't have polarity (positive and negative). In this case, it will act like a piece of wire when switched on, and open circuit when switched off. It has to be wired in series with whatever you want to control.
The switch should be in the nongrounded line, whether it is positive or negative. If the circuit is floating or isolated from ground, it doesn't matter.
If the terminal isn't labeled as “Common,” it will have a black or copper terminal on the bottom side of the switch. Then, connect the red wire to a terminal on the top side of the switch. Red is a traveler wire and can be connected to the left or the right upper terminal.
How Do You Wire 2-Way Switches For 1-Way Switching? Most two way switches have a Common terminal, as well as an L1 and L2 terminal. For two way switching you will need to connect both L1 and L2. For one way switching, as you have one less connection, you only need to use the L1 connection.
How does a toggle switch work? When the switch operator pushes the toggle (the actuator), the armature switches the contact into position to start or stop an electrical flow. In simple terms, when the toggle is pushed it can switch a device on or off.
There are two basic types: maintained contact and momentary toggle switches. A maintained switch changes its position when actuated and will remain in that position until actuated again, such as an ON/OFF function. A momentary toggle switch is actuated only when someone is operating the switch.
The appliance will operate normally without the ground wire because it is not a part of the conducting path which supplies electricity to the appliance. In fact, if the ground wire is broken or removed, you will normally not be able to tell the difference.
What happens if you don't run a ground wire?
Grounding helps protect you and your home from the dangers of damaged circuits or electrical overloads. When power surges happen, the excess electricity introduced to the system could leap out of the wiring. Without electrical grounding, this stray voltage could start a fire, damage appliances, or shock bystanders.
What to do When there is Nothing to Attach the Ground Wire. When you have a ground wire and there is no place to attach it then place a wire connector over the end, coil up the ground wire and push it back into the electrical junction box. IMPORTANT: Never cut the ground wire off.

If a light switch is wired up wrongly, a short circuit may takes place if you give phase and neutral to the switch terminals. Always connect neutral wire to the one terminal of the light and phase to the one terminal of the switch and off wire to the other terminal of the switch to the light other terminal.
So the negative connection of the supply in this case would be called "common" or 0V. 0V because all voltages within the circuit are measured from that common point, which also happens to be the supply's negative pole.
One common issue with electrical outlets is reverse polarity, also known as "hot-neutral reversed." In this condition, the outlet has been wired incorrectly, altering the flow of electricity. While the outlet will still be able to provide power to your electrical items, it is also present a greater shock hazard.
Which side of a 2-prong plug is positive? Because we use A/C current, prongs don't have have a positive and negative. Instead, the two prongs have a 'hot' and 'neutral' side. The wider prong connects to the neutral wire and the smaller prong smaller prong is the hot side of the circuit.
In AC household common plugs, there are no positive or negative “terminals”. The smaller prong is the HOT side of the circuit while the larger prong is the return or neutral side of the circuit.
Take a look at your outlets. If they have holes for only two prongs, they're ungrounded. Ungrounded outlets don't have the necessary ground wire to protect you from possible surges of electricity. The ground wire helps prevent electrical shock, electrical fires and damage to electronics.
If your house has two prong outlets with metal boxes, it is possible you can ground your outlets without overhauling the wiring. To find out whether the metal housing is grounded, purchase a circuit tester.

What are the pins on a toggle switch?
Pin 1 is where the rocker switch receives the input power. Pin 2 is where the accessory that the switch is going to turn on is connected. Pin 3 is where the switch is either connected to ground or left open. This is the pin where the rocker switch receives its voltage.
Wiring a One Way Switch
The other terminal is marked as L1 and is the output to the light fixture. When you're wiring decorative light switches such as chrome or stainless steel etc, you'll find that the switch will also have an L2 terminal which means it's a two way switch.
A type of electric switch which has two terminals and is used to conduct current only in one direction is called a one-way switch. A two-way switch is the one which has three terminals and can conduct current in either directions. One way switch has two terminals.
Without the ground present, problems with your outlet may cause arcing, sparks, and electrical charge that can spawn fire along walls or on nearby furniture and fixtures. Health hazard. Ungrounded outlets pose real risk of shock to people operating the electronics and appliances plugged into the outlet.
According to the National Electric Code, two-prong outlets are allowed in homes as long as they are properly working. If you choose to replace your two-prong outlet, you do not have to upgrade to a newer model. If the two-prong outlet is properly functioning and tested, you may keep it in your home.
Both kinds of outlets feature hot and neutral wires, but the big difference is that three-prong outlets have a grounding wire, while two-prong outlets don't have one.
A pole refers to the number of separate circuits a switch can control, a single pole switch can operate one circuit whereas a double pole switch can control two circuits. A throw refers to how many positions can be activated by a switch.
First, connect the common wires to the common terminals labeled on both new switches. If the terminal isn't labeled as “Common,” it will have a black or copper terminal on the bottom side of the switch. Then, connect the red wire to a terminal on the top side of the switch.
A single-pole switch has two brass terminal screws on the side that connect to the electrical circuit's black (“hot”) wires.
Switches don't have polarity (positive and negative). In this case, it will act like a piece of wire when switched on, and open circuit when switched off. It has to be wired in series with whatever you want to control.
What is the white wire on a toggle switch?
Depending on toggle switch configuration, either the red wire or the black wire will be hot if the light is on, but not both. White wire: Still considered the neutral wire, the white wire from the 14/3 cable serves to carry electricity back to the power source to complete the circuit.
