How To Select And Install Waterproof Pushbutton Swich
Electronic products are often concerned with several aspects: current overload, will cause circuit components burned out short circuit; Circuit water, also can make electronic components caused by short circuit; A large electromagnetic pulse can break through the internal components of an electronic product, such as the capacitor resistance, thus disabling the electronic product. So waterproof is the key direction of electric appliances now, so switch is a very important breakthrough. Like a cell phone. Even if the shell is good, there is always a gap between the keys and the shell, the water is seamless. Working principle of waterproof button switch is the application of the advantage of low voltage rectifier filter circuit, after the high frequency transformer step-down start pulse voltage to use the same diode rectifier and filter and capacitor, and the rectifier part using ac impedance of capacitance also cannot have the too big, it won't be able to filter out the high frequency ac components, so the selection of capacitance not only the capacity is larger, Low AC resistance is required. In addition, 1 or 2 large inductance coils with magnetic cores can be seen to filter out high frequency AC components together with filter capacitors to ensure pure DC output.
1.IP grade up to IP66, with Australian standard certification, anti-corrosion waterproof button switch socket suitable for industrial environment.
2. Free and simple combination, simple and firm installation.
3. The performance meeting your needs for switching devices in various harsh environments; Waterproof, dustproof, chemical corrosion resistant, uv resistant, impact resistant.
Waterproof button switch installation switch also has certain requirements, the choice of switch installation position should be appropriate, the kitchen switch is not installed on the hearth, to prevent overheating; Toilet bath bully switch in the installation should stay a few centimeters more position, because this switch is generally larger than the light switch circle, if the difference a little bit not installed into the trouble; In addition, do not install the switch in too close to the place of water, if installed in the balcony of open mode remember to use switch socket special splash cover.
Waterproof button switch an electronic switch, when used gently click the switch button can make the switch on, when the release of the switch is disconnected, its internal structure is to rely on the metal shrapnel force elastic movement to achieve on and off.
Waterproof button switch is not contact with how much power can change the state of the switch contacts, so contact capacity is small, and the structure is simple, can only maintain the original state after removal of switch power, that is to say, is a with a small force can push, single contact without lock button switch, at present, membrane switch, small micro switch can be light touch switch, The structure mostly uses two mutually insulated film printed conductive circuit, by pressing the line to connect with each other, or the use of thin elastic metal made of butterfly spring, press the spring to connect the printed circuit.
A reliable button switch, for the life of the whole product, is also very important. Like computer keyboards, remote controls and so on. If it is inferior light touch switch, after frequent press will make metal shrapnel fatigue loss of elasticity and failure. Therefore, the choice of switch is very important. Waterproof light touch switch is good or bad influence factors, the main key is waterproof button switch protection, solderability, conduction reliability, life, feel, production process and installation size and other factors.
By the above electronic switch manufacturer Yeswitch electronics for you to bring some common sense about waterproof button switch. Consumers should have a more comprehensive understanding of the product before buying it.
