what wire goes to the black screw on a light switch

When it comes to wiring a light switch, knowing what wire goes to the black terminal is an important step. This terminal is responsible for completing the circuit, allowing the light to turn on and off. Understanding how the wires connect to the switch and their purpose will ensure a safe installation and that the switch works properly.

Installing a light switch is a fairly straightforward task, but if you’re new to it, the process could seem a bit daunting. That’s why it’s important to thoroughly understand the wiring before attempting to install a switch. One of the most important pieces of information is knowing which wire should go to the black terminal on the switch, as this is what will allow the circuit to be completed and the light to be switched on or off.

To understand what wire should be connected to the black terminal on the switch, it’s important to first understand the basic concepts of wiring. An electrical circuit is composed of a power source (such as a battery), a circuit breaker, and a load (in this case, the light). The circuit must also have a conductor (the wire) that connects these elements together, allowing electricity to flow. The wire will typically be either white or black.

The white wire is the “neutral” wire, and carries the electricity back to the power source. The black wire is the “hot” wire, and carries electricity from the power source to the load. When the switch is in the “on” position, it allows the current to flow through the black wire to the load, turning the light on. When the switch is in the “off” position, it stops the current from flowing, turning the light off. Therefore, the black wire should always be connected to the black terminal on the switch.
