Most people are seeing the process of soldering a push button switch as very complicated and technical. In other words, they either don’t consider the option of giving it a try or are fed up of the entire process. It doesn’t really matter the category you belong to as having a push button soldered isn’t supposed to be difficult. You are only being limited by the lack of quality information available to help such process become successful.
Are you struggling in the process of soldering a push button? Do you know that such process is very easy to carry out once you understand how to do it correctly? The good part is that there won’t be any need to bother about such again as this post will be helping you out today. It will be explaining how to solder a push button switch in the most effective manner today.
The truth is that there is a wrong way and right way to go about such a process. Details below will be helping you understand the latter method in order to avoid the problem of having to start all over again. Just ensure to read everything carefully.
What is a push button switch?
Push switch usually contains electric mechanism through which something can either be turned on/off. Just like switches, they can be used in powering devices. However, such is done in a different manner. For instance, there has to be a button which is pushed for current to flow through such device. You might not have noticed but these switches are used in various ways. It is a small and sealed mechanism which helps to ensure electrical circuit is completed once pressed.
Most of the time, they have been built to contain metal spring. Whenever such is on, it means the metal spring is contacting two wires. In such instance, electricity is allowed to flow. Once it goes off, such spring will be retracted thereby making current flow to be interrupted. In this case, the two wires aren’t contacting each other again. In most cases, a push button switch is usually made with plastic materials (non-conducting). There are times when it can be constructed using metal materials. It all depends on the kind of contact they are expected to make.
There are two types of contacts that can be made using a push button switch. These are momentary contacts and latching contacts. Momentary contacts mean that current will flow as long as your hands are on the switch. This is usually common with phones that use buttons. You will notice that there is contact whenever they are pressed. Calculators and door bells can also come under this group since they operate the same way.
In this case of latching contacts or non-momentary contact, just one push of the button is required for such device to be powered on/off. An example is television since its power buttons is pressed once to have it turned on/off.
How to solder a push button switch
Before going into the main details on how a push button switch can be soldered, it is important you know that these switches are usually available in various shapes and sizes. It all depends on the type of project you are embarking on.
The first thing you need to know is that push button switches usually have terminals. You will need a wire for the soldering process to be successful. The reason why solder is better is that it will help the wires to be strongly attached to each terminal thereby ensuring effective contacts.
In case you don’t know what terminals are in a push button, the diagram above will be of great help. You can see that it has Terminal 1 and Terminal 2. These are the points where the wires will be attached to. Just put each wire on the terminals. For instance, one wire should be put on terminal 1 while the other wire should be put on Terminal 2.
At this point, you need a soldering iron, lead (solder) and plier. The soldering iron will be used in heating the wires on each of the terminals. This will be done through the lead or solder. The plier will be used in opening the wires in order to ensure you are using the parts which conduct electricity.
Now connect your solder iron to a socket in order to have it heated up. Once it has been connected for about 5-10minutes and hot enough to melt the lead, have it unplugged from the socket.
Put each of the wires on the terminals as explained above. After that, the lead should be placed on the wires. Now, put the hot soldering iron on the lead. The heat being produced should be enough to melt it. That is to say, the lead will melt on the wires to make them firmly attached to the terminals.
Allow it to cool for some few minutes before touching in order to avoid unnecessary injury. This process is very simple and can be done by anyone.
There are people who may find the above process a little bit complicated. There is another way you can use in connecting your push button switch to any device. This involves passing each of the wires through the holes in the terminals.
After the wires have been passed through such holes, they should be twisted to ensure firm contact. This will make your device function whenever the button is pressed. The only disadvantage with this method is that the wires may likely loose contact in the nearest future.
Based on the above, it can be seen that the process of soldering a push button switch isn’t complicated or difficult in any way. You just need to understand what is required in each step. If it happens that you can’t grasp what has been explained above, it won’t be a bad idea exploring the alternative method above.
