What is a Door Switch?

Door switches simply refer to sensors devised to indicate whether a door is closed or opened. They are normally attached to the door frame, and their opening and closing is what determines whether the electrical contact circuit will be made or broken. It will interest you to know that over the years, door switches have turned out to be a rampant signature within residential and official spaces. 

These switches have been remarkably excellent in the way they function. While what we have now is almost perfect, one would expect that door switching systems will keep improving as more people use them.

How a door switch works?

This has always been an interesting subject for anyone who loves to get in on the door switch business. These items can only be fully applied when you understand how the switch functions. Just like the position switches you have with gates, door position switches function by employing magnetic and magnetic sensitive switches. You place a magnet atop the door, while the switch will be mounted on the frame of the door. That way, anytime there is proximity between the magnet and magnetic switch, a circuit is completed, and an action will happen. 

A door position sensor?

These sensors are designed to remotely verify the status of the door via a web interface or inform you the door is open, through the help of an alarm. Like we have stated earlier, such sensors are composed of two major parts, one magnet and one switch that has terminals for connecting the wires that will channel the signal. In most instances, the magnet is usually mounted onto an access panel or a door, while the switch sits on the frame. With that perfect arrangement, the switch and the magnet will be able to make and break contacts as expected. 

Why door switches have become popular?

The reason why door switches have turned out to be popular in recent times is something that transcends the world of innovation. One reason why magnetic door switches have prevailed over so many other types of switch is because they are inexpensive. You do not need to have heaven and earth before you can acquire a good and long-lasting door switch. Reliability is another factor that has made these switches into leading products. They are to be relied upon due to the way they have been designed to work. 

Different models

Door switch models are so many that people get confused when they try to make a purchase. While that is entirely true, you must understand that all the models have the same working principle. They may differ a bit in their material quality, but their mode of operation is practically the same. 

The model you finally end up with will only be a question of preference, and not really because it has a special way of working. Having said that, you may also want to watch out for the history of the brand you are going for. That will be absolutely necessary so you can get something that will last for a long time. 

Maintenance of door switch

All electrical and electronic devices do need some form of maintenance as time flies by. However, whatever everyone wants to know is how often these maintenance should be carried out so that the lifespan of the switch will not be compromised. 

How often you need to maintain your door switch will depend on how regularly that switch is being used. While we have gotten that out of the way, trying to do the maintenance yourself can be a tricky task. If you want the door switch to be properly serviced for it to function appropriately, you have to ensure a professional comes in to do the job. 

Where can you use a door switch?

Indoor spaces are most ideal for this type of door switch. So long as users will like to know the status of that door, a door switch will gladly do the honors. That way, you will not be waiting or thinking that the status of the door is what you are assuming. Instead, you would know the true status, depending on whether the switch is a normally open type or normally closed type. 

How to install a door switch?

There are a couple of instructions one is supposed to abide by when undertaking a door switch installation. A couple of strict electrical codes and regulations are some of the first things anyone undertaking such installations is meant to understand. 

Disconnect from your power source before you even dream of starting anything. Many people have flouted this rule because they felt it was not necessary; they have only had themselves to blame. An electric shock could very well be the outcome.

Do not mount the switch on a metal-based door. That could also risk an electric shock, and could harm users eventually. 

Make sure the switch wires are properly connected, otherwise its operation might be compromised. 

Fasten the door switch tightly to the frame of the door, so the switch will lap with the frame. 

The switch and magnet should be correctly installed so they can make the necessary contact when the door is brought closer. If both of them do not align during installation, the make and break contact will be gravely affected.

The level of competition in the door switch industry is very stiff at the moment, and that is not helping the customers in any way when it comes to making choices on which brand to stick to. Like we have rightly pointed out in the course of the article, all door switch models are almost the same. Their principle of operation is similar across board. The only thing that might separate them could be the quality of materials used for manufacturing the switch. Door switches are great for indicating a door status, as to whether it is open or closed. Due to its inexpensive nature, you are very likely to see one that fits with your budget.
