There are many types of touch switches, but how can we distinguish the performance and types of touch switches? Below, we will briefly explain the working principle of the waterproof light touch switch. Its principle is to turn on or off the circuit by pressing a button. However, the waterproof light touch switch will not malfunction or short circuit the circuit even in the presence of water or immersion. The specific details are as follows:
The waterproof touch switch that we are familiar with is a switch that can be soaked in water or rain without malfunctioning under normal circumstances. The rating of the waterproof switch is usually IP67, which means it can provide complete protection against dust in the air. Sometimes, it can also be at a depth of about 1 meter underwater, and at room temperature, it will not be damaged for about 30 minutes
On the other hand, the working principle of a waterproof touch switch is that when you press it down, there is a short circuit on all four legs. A switch with two legs is called a short circuit on both legs. Generally speaking, when you press it down, it will conduct and pop up to disconnect. If you press it twice to open or close, it cannot be achieved by touching the switch lightly. It is necessary to connect the signal of the touch switch to other circuits, such as the IO port of the microcontroller. Check if your switch is pressed twice. If it is detected that you press it twice, it can perform the circuit on and off function. Therefore, the function of the switch is to conduct and disconnect twice, even if you do not need to short circuit or disconnect the switch wires twice, it can still achieve the function. of.
Due to its small size and light weight, waterproof touch switches can be widely used in household appliances, such as digital products, remote controls, audiovisual products, medical equipment, fitness equipment, communication products, currency verification pens, security products, toys, household appliances, computer products, laser pen buttons, and so on. However, waterproof touch switches also have their shortcomings. Frequent pressing can fatigue the metal spring and cause it to lose its elasticity and fail. So now most electrical buttons are replaced directly with conductive rubber or pot switch hardware clips, such as remote controls, computer keyboards, etc.
So we often say that a waterproof touch switch is an electronic toggle switch. Simply lightly pressing the switch button during use can turn the switch on. When the hand is released, the switch will turn off. Therefore, its internal structure relies on the force of metal springs to achieve on and off.
