Will the light up when the switch is connected

Yes, a properly connected light switch completes the circuit, allowing electricity to flow to the light fixture and turning it on.How a Light Switch WorksA light switch controls the flow of electricity to a light fixture by opening or closing the circuit. When the switch is on, it closes the circuit, allowing current to flow from the power source through the hot wire to the light fixture, illuminating the bulb. When the switch is off, it opens the circuit, stopping the flow of electricity and turning the light off .Wiring ConsiderationsFor the light to turn on when the switch is connected, the wiring must be correct:Single-pole switch: The most common type, it has two terminals. One wire brings power from the breaker (hot wire) and the other goes to the light fixture. The switch interrupts the hot wire to control the light .Three-way or four-way switches: Used when controlling a light from multiple locations. Proper connection of traveler wires is essential for correct operation .Power-through vs. end-line wiring: In power-through wiring, electricity goes to the switch first, then to the light. In end-line wiring, power goes to the light first, then to the switch. The switch must be connected to the hot wire to control the light properly .Potential IssuesEven if the switch is connected, the light may not turn on if:The switch interrupts the neutral wire instead of the hot wire, leaving the fixture live but not illuminating the bulb, which is dangerous .The switch is faulty or worn out, failing to break or complete the circuit .The bulb is burned out or the fixture has a wiring fault .Safety TipsAlways turn off the circuit breaker before connecting or inspecting a switch. Use a voltage tester to confirm the power is off before touching wires . Properly connecting the switch to the hot wire ensures the light will illuminate safely when the switch is turned on.
