There are many types of switches, of which tact switches are one of them. This kind of switch plays a very important role in our lives. Then let's take a look at what kind of convenience this kind of switch can bring us. .
Televisions, video phones, rice cookers, DVDs, smart wearables, audio equipment, etc. are all electrical appliances that can be seen everywhere in our homes. There is an indispensable thing on these electrical appliances, that is, a touch switch. If there is no switch , The use of electrical appliances is definitely a tricky problem.
The other is the voice recorder and the camera, which are also equipped with this switch, so that the switch can be turned on when the criminals inadvertently record important words and deeds, which plays a very important role in solving the case.
Whether it is a person who leads an ordinary life or a person with a shining life, they can see the tact switch around them, as long as you can see the electrical appliances or use the Ke tact switch technology products, you can see To this switch.
At present, the use of switches is very widespread, and because most of the switching elements are basically some type of micro-patch light touch switches, we may often overlook some details of the switches in daily use. Therefore, it will cause many failures of the switch. Then whether we are a technician or an ordinary person, we still need to understand the basic use common sense of the micro patch touch switch that we use every day. Then about the details The explanation is as follows.
Basic use common sense of miniature patch tact switch.
Use common sense one.
Regarding the current load of the switch, the switching capacity of AC and DC circuits is generally very different. In order to prevent potential safety hazards, please use it within the rated current value of the touch switch.
Use the common sense two of the touch switch.
When the SMD touch switch is operated and installed, the metal shrapnel inside should be careful to ensure that it is not scratched, so as to avoid the situation that some keys cannot be induced to be energized during the use of the switch.
Note the use of common sense three.
Tact switches should not be used in high-temperature environments, because in high-temperature environments, the internal metal components of the switch are heated and cause accelerated aging. Then it will easily cause the switch to cause some failure problems, and secondly, it will Resulting in speeding up and reducing the service life of its switch.
Use note four of common sense.
Do not install the switch too close to water. For example, when installing the switch in the kitchen, bathroom, etc., be sure to install the switch splash box. Otherwise, if water splashes into the switch, it will cause short circuit and other problems in the circuit. , Then it is possible to burn the switch directly.
Use common sense five.
Touch the switch installation process to ensure that the key switch is clean and tidy. If there are some dirt, debris, or large dust particles, please be sure to clean it before installation to avoid affecting the normal operation of the switch.
Use note six of common sense.
In the use of some key switches with indicator lights, it is necessary to pay attention to the temperature and voltage values of the circuit board to avoid overheating of the indicator lights, which may cause indicator failures and affect the performance of the switch.
Use note seven of common sense.
Regarding the installation of the switch, do not install multiple lines in parallel. Otherwise, when multiple switches are running at the same time, the starting current is relatively large, which will cause the switch to not be able to bear it, which may cause the switch to be burned.
Pay attention to common sense eight.
Also, before using the switch, it is best to make sure to check whether the internal pin points of the switch are connected incorrectly, so as to avoid problems such as malfunctions during the use of the switch.
