First of all, the correct term is 'line' and not'phase' wire. The reason a switch is always placed in the line conductor, rather than in the neutral conductor, is that its function is not simply to break the circuit, but also to ensure that the circuit's load is disconnected from the line potential. If the switch were to be placed in the neutral conductor, it would still break the circuit, but the load will still be at line potential and present a shock hazard to anyone attempting to work on the load (e.g. to remove a lamp from its holder).
because its much safer to switch the hot wire then the neutral wire because if you are working on a light fixture for example and the switch is off if you ground yourself out to the neutral you become the load or return. a neutral shock can me more dangerous at times
The neutral wire from the chain switch is connected to the white wire from the ballast. They should be connected together using a wire nut to ensure proper circuit completion and safe operation of the light fixture.
You should never switch the neutral wire. The neutral of the appliance should be connected directly to the neutral wire leading to the service panel neutral bar.
Answer for USA, Canada and countries running a 60 Hz power supply service.The white wires are the neutral wires. One of the black wires is the "feed" hot wire coming from the circuit's breaker on the incoming power panel.The other black wire is the "switched" hot wire going to the load. (The light or whatever appliance the switch is controlling.)If you don't know how to tell which black wire is which, the hot is usually the wire connected to the top screw on the switch. In Canada, there is a rule that all hot wires are to be connected to the top of switching devices.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Connect the black wire to the single switch hole, the brown wire to one of the holes on the double switch, and the gray wire to the other hole on the double switch. The earth wire should be connected to the grounding point on the light switch. Make sure to follow proper safety procedures and consult a professional if you are unsure.

A simple wiring diagram for a light switch involves connecting the power source to the switch, and then connecting the switch to the light fixture. The power source is typically connected to the switch through a black wire, and the switch is connected to the light fixture through a white wire. A ground wire is also connected for safety.
There are two common ways to wire a 3-way switch in a lighting circuit: the "California" method and the "conventional" method. In the California method, the hot wire is connected to the common terminal of one switch, while the travelers are connected to the other switch. In the conventional method, the hot wire is connected to the common terminal of one switch, and the travelers are connected to the other switch in a different configuration.
In a light switch circuit, the line is the wire that brings power into the switch, while the load is the wire that carries power from the switch to the light fixture. The line wire is typically connected to the power source, while the load wire is connected to the light fixture.
The neutral wire from the chain switch is connected to the white wire from the ballast. They should be connected together using a wire nut to ensure proper circuit completion and safe operation of the light fixture.
The speed sensor wire is connected to the speed sensor and goes to the speed sensor relay switch. The speed sensor relay switch is connected to the computer by a separate wire.
A 4-wire light switch typically includes a ground wire, a hot wire, a neutral wire, and a traveler wire. The wiring diagram for a 4-wire light switch will show how these wires are connected to the switch terminals to control the light fixture.
High or "wild" leg phase to ground.
You should never switch the neutral wire. The neutral of the appliance should be connected directly to the neutral wire leading to the service panel neutral bar.
To properly connect the 3 black wires to a light switch, you should first identify which wire is the hot wire, which is the neutral wire, and which is the load wire. The hot wire should be connected to the black screw on the switch, the neutral wire should be connected to the silver screw, and the load wire should be connected to the brass screw. It is important to turn off the power before making any connections and to follow all safety precautions.
The common wire in a switch is used to provide a continuous flow of electricity to the switch, allowing it to control the flow of electricity to the connected device or light fixture.
