If you are seeing a spark then the switch should be changed out right away. The spark is created by bad contacts within the switch its self. These bad contacts will create heat and eventually destroy the switch. Make sure that the rating of the switch is greater than the load that is connected to it. The only time a switch might draw an arc is when it is opened but it should never arc when closing. Yes there should be a spark when a switch is put on.
When a light switched is turned on the circuit is usually closed.
Unless the switch has a light to indicate the switch is turned on, there is no neutral connection to a single pole switch.
I recently tried this. Power surges were ruining a security light over the garage. I thought it was overloading the light sensor which turned the light on at night. So I bypassed the circuit board in the light and put a light switch inside the garage. Most CFL bulbs have the starter built-in, and I thought this was the case on this security light. Not so. The circuit board was also the starter. I had to switch to a regular CFL in lieu of using the extremely bright bulbs (without starters) made for this light.
The scratchy noise when turning off a light switch is likely due to a phenomenon called arcing. Arcing occurs when the electrical current jumps between the contacts inside the switch as it is being interrupted, creating a popping or scratching sound. It's a normal occurrence in some switches but can be a sign of wear and tear, so if the noise becomes excessive or the switch feels hot, it's a good idea to have it checked by an electrician.
If the light has a dimmer switch and it's not working, first check if the dimmer switch is in the correct position and hasn't been accidentally turned off. If the switch is on and the light still isn't working, there may be an issue with the dimmer switch or the light bulb itself. Try replacing the bulb or checking the dimmer switch for any malfunctions.
A door switch may be broken or out of adjustment or the dome light switch on the dash is turned on.
Current flows through a wire when a light switch is turned on.
A light switch can get hot when turned on because of the flow of electricity through the switch. This flow of electricity causes resistance in the switch, which generates heat as a byproduct.
When a light switched is turned on the circuit is usually closed.
The light switch on a microscope is used to control the intensity of the light source. It allows the user to adjust the brightness of the light passing through the specimen to optimize the viewing conditions for better clarity and contrast.

The most likely answer is that the parking light switch on top of the steering column is turned on. --Ken The parking light switch is turned off,the engine is turned off,they are still flashing
The basic principles of switch wiring involve connecting the switch to the power source and the light fixture in a circuit. When the switch is turned on, it completes the circuit and allows electricity to flow to the light, turning it on. When the switch is turned off, it breaks the circuit, stopping the flow of electricity and turning off the light.
The power to light switch in electrical circuits works by allowing or interrupting the flow of electricity to the light bulb. When the switch is turned on, it completes the circuit, allowing electricity to flow and light up the bulb. When the switch is turned off, it breaks the circuit, stopping the flow of electricity and turning off the light.
Either there is a loose connection where the wires are attached to the switch, or there is a bad connection inside the switch itself. Turn the breaker off that controls that switch. Remove the cover plate. make sure the wires are tightly connected. If they are tight, replace switch.
The purpose of the neutral wire in a light switch circuit is to provide a return path for the electricity to flow back to the power source once the switch is turned on, completing the circuit and allowing the light to turn on.
An electric light switch works by interrupting or completing the circuit that allows electricity to flow to a light fixture. When the switch is turned on, it closes the circuit, allowing electricity to flow and the light to turn on. When the switch is turned off, it opens the circuit, cutting off the flow of electricity and turning the light off.
