We used Incan Electric to install a new electrical panel at our property in Racine. They were prompt, knowledgeable, and reasonably priced. Although there was a small issue during the installation, they quickly resolved it to our satisfaction.

I recently had Incan Electric install outdoor lighting at my home in Oak Creek. They did a great job and left the work area clean when they were finished. I deducted a star because it took them a bit longer than initially estimated to complete the job.

Incan Electric is the best electrical company I've ever dealt with. They rewired my entire home in Waukesha and kept me informed throughout the process. The technicians were polite, hardworking, and took the time to answer all my questions.

I called Incan Electric to fix a faulty outlet in my home in West Allis. They came out quickly, but the repair was a bit pricier than I expected. Overall, they got the job done, but I wish the cost had been more reasonable.

Incan Electric did a good job installing a backup generator at our home in Franklin. They were punctual and professional, but there was a slight miscommunication about the final cost. Once we cleared that up, we were happy with their work.

We had Incan Electric upgrade our electrical system in our Caledonia home. They were thorough and professional, but we had a small hiccup with scheduling. In the end, the job was completed successfully, and we're happy with the outcome.

## What is a Light Switch
It is a device that completes or breaks a circuit to regulate the passage of electrical current through it. To turn on or off the lights or other electrical items, it is normally connected only to the hot wires. The neutral wires may also need to be connected to since they may have extra functions like a lit toggle or a timer. Most contemporary switches also have a grounding connection for security. Older versions might not have this feature.

## Common types of light switches

1. One-way switches
2. Two-way switches
3. Crossover switches
4. Toggle switches

## Common problems of light switch

### There is a delay when turning on the lights

If there is a delay between flipping the switch and the light coming on or going off, or if the light flickers before staying on, it may indicate that its internal components are wearing out. It could mean that the electrical contacts within the switch are not making the connections they should be. Even if the problem occurs infrequently, it could be caused by a loose connection or a short circuit.

### Flickering Lights

A light bulb may flicker unexpectedly or when movement is nearby, and there can be various reasons for this. The bulb may be loose and needs tightening, or there is a loose wire connected to the bulb or switch.


### Mechanical problems

Mechanical failure is a common cause. If the switch is not working properly, it needs replacement or repairs. Signs of mechanical failure include the switch not turning on or off, no matter how many times you switch it. Replacing it should always be done by a professional. Attempting to do it yourself can be dangerous and lead to electrical shock or injury.


### Sparks
It is normal to see some sparks when turning off a switch as the electricity arches between the contacts. However, if the spark is large, produces a loud noise, or is accompanied by smoke, this may indicate a problem that needs addressing.


### Noise
A buzzing, sizzling, or popping noise can indicate a loose wire or an issue with the switch. Dimmer switches may make this noise because of the way dimmable bulbs work - dimming can cause vibration in the filament of the bulb. Check the bulb before looking into any issues with the switch.



### Tripped circuit breakers 
Determining the source of a tripped breaker or burned-out fuse can be difficult as it may not always be linked to a single switch. A defective one may be unresponsive, but the issue could also be with the fuse or breaker. If there are no problems with the electrical panel, it may need some replacement.
