Today to explain to you some of the waterproof button switch, the real quality of waterproof button switch is what, are introduced to you.
Electronic switch products are most concerned about several aspects: current overload, will cause circuit components burned short circuit; circuit water, will also cause electronic components short circuit; excessive electromagnetic pulse, will break through the internal components of electronic switch products, such as capacitor resistance, so that electronic switch products scrap. Then in the waterproof aspect is now the key direction of electrical appliances, then the switch is a very important breakthrough. For example, a mobile phone. Even if the shell is done well, there is always a gap between the key and the shell. The working principle of the waterproof button switch is to use the advantage of the low voltage rectifier filter circuit. The pulsating voltage after the high frequency transformer step-down also needs diode and capacitor to rectify and filter, and the capacitor used in the rectifier part can not have too much AC impedance, otherwise the high frequency AC can not be filtered out. Therefore, the selected capacitor not only has a large capacity, but also has a low AC resistance. In addition, 1 or 2 large inductance coils with magnetic cores can be seen to filter high-frequency AC components together with the filter capacitor to ensure the output of pure DC.
1. IP grade up to IP66, with Australian standard certification, anti-corrosion waterproof button switch socket for industrial-grade environment.
2. the combination is simple and easy to install.
3. Advantages to meet your requirements for switchgear in a variety of harsh environments; waterproof, dust-proof, chemical corrosion-proof, UV-proof, anti-impact.
Waterproof button switch installation switch is also a certain requirement, the switch installation position should be properly selected, the kitchen switch should not be installed in the kitchen, to prevent overheating; bathroom bathroom switch in installation to leave a few centimeters more position, because this switch is generally larger than the light switch, if it is almost not installed. Do not install the switch too close to the water. If you install it on an open balcony, remember to use a special splash cover for the switch socket.
Waterproof button switch is an electronic switch which can be switched on by pressing the switch button lightly when used. When the hand is loosened, the switch is disconnected, and the internal structure of the switch is realized by the force elasticity of the metal shrapnel.
Waterproof button switch is to change the state of the switch contacts without much contact, so the contact capacity is very small, and the structure is simple, the switch force can only be removed to maintain the original state, that is to say, quite a small force can be pressed, without locking the single contact button switch, at present Membrane switch and small micro-switch can be regarded as light touch switch. The structure mostly uses two insulated thin film printed conductive circuits, which connect each other by pressing, or uses butterfly-shaped elastic sheets made of thin elastic metal to connect the printed circuit.
How important is the selection of waterproof button switches? A good button switch is also important for the life of the whole product. For example, computer keyboard, remote control and so on. If it is a poor quality light touch switch, after frequent press will make the metal fragment fatigue loss of elasticity and failure. Therefore, the selection of tactile switches is very important. The key factors influencing the quality of waterproof light touch switch are the protection, weldability, conduction reliability, life, feel, production process and installation size of waterproof button switch.
