There are many kinds of touch switches. The basic principle is to press the button to access or break the power switch of the power supply circuit, but the waterproof power switch will not work even in the condition of water seepage, and the power supply circuit will not short-circuit failure. The main contents are as follows.
We are familiar with the waterproof touch Pushbutton switch, is generally able to soak in the water or rain will not fail the switch, usually waterproof switch grade is IP67, which means that the dust in the air to play a complete protection role. Sometimes, it will be a meter or so in the water. At room temperature, it does not damage easily for about 30 minutes.
On the other hand, the working principle of waterproof beat switch is that when you press, four feet short circuit, there are two feet of the switch two feet short circuit, generally press to turn on the spring and close, can not double click and double click switch case, touch switch signal becomes other circuits, such as a switch. If it detects whether the switch is double-clicked, it can perform the function of connecting and disconnecting the circuit, so the function of the switch is connecting and disconnecting twice, even without short-circuiting or disconnecting the switch wire can also play a function.
Waterproof touch pushbutton switch due to its small size and light weight, so it can be widely used in household appliances, such as: digital products, remote control, audio and video products, medical equipment, fitness equipment, communication products, banknote pen, security products, toys, household appliances, computer products, laser pen keys and so on. But waterproof touch switch also has its shortcomings, frequent press will make metal shrapnel fatigue so that the loss of elasticity and failure. As a result, most of today's electronic buttons are immediately replaced with conductive rubber or tablet power switch hardware configurations, such as controllers and computer keyboards.
So we also often say that waterproof touch pushbutton switch is a kind of electronic Toggle Switch, as long as in use gently press the switch button can make the switch on, when loosen the hand when the switch will be disconnected, so its internal structure is to rely on the metal shrapnel force elastic movement to achieve on and off.
