Anti-damage switch (metal button switch) - indispensable in daily life

The use of technology is increasing around the world. Trends in technology use are increasing in many public Spaces, indoors and outdoors, as businesses and the public sector scramble to control costs and provide customers with better experiences.
This approach has brought many benefits, but it has also created a series of challenges. This includes the human machine interface (HMI), which generally consists of a series of push switches. As a rule, we take great care to protect the devices we own, but these shared devices can be subject to malicious or unintentional misuse.
To that end, planners can now use extremely rugged switches to develop human-machine interfaces for shared technologies that can stand the test of time.
What criteria planners should consider when specifying switches for rugged human-machine interfaces.
We need damage-proof switches.The metal push button switch.
Basically, in order to complete the use of the system, the system requires users to input information to acknowledge the operation they wish to complete, or to supply information to the system. Because speech recognition technology is still in the early stage of development, the use of various types of tact switches is still the preferred method of human-machine interface development.
When technical equipment is located in an unsupervised area and operated by someone other than the equipment owner, it is likely to be misused. Individual users sometimes select for malicious damage to equipment for various reasons. Even legitimate users of the equipment may not appreciate it. They will carelessly push the tact switch hard, and then shorten the service life of equipment, especially technology with a human interface. It is obvious, for example, that a precise substrate switching matrix in such cases is often not long term.
As the number of such devices increases, so does the demand for high-strength human-machine interfaces. In addition to the family day, our daily work, simply can not do without a variety of press switch operating system.
For example, if you're hitchhiking somewhere, you'll notice that the pump at a gas station usually has a button to pick the gas number. If you're in an electric car, you'll find that the charging station also has buttons that input commands and turn the charging process on/off. Push-button interface devices are needed at service stations to inflate tires, clean or clean our cars.
Even if we travel by train instead of car, we see more buttons, more kinds of buttons; For example, when opening a car door, going to the bathroom, or using an intercom device, buttons are used. When buying a ticket, the machine may also have a rugged man-machine interface.
When we arrive at our destination and may need some cash, you'll find that active machines also have high-strength keyboards to help prevent damage. The building we are going to may also have access control or intercom system, after entering the building, there are also buttons in the elevator to choose the floor.
High strength human-machine interface special switch
Special high-strength human-machine interface switches (which can accept damaging operation by rough use or malicious damage) differ from standard switches in terms of manufacturing materials and methods.There is the metal push button switch.
Damage resistant switches generally choose metal structure, the most commonly used is stainless steel, but nickel plated (Ni) brass is also common, and sometimes anodized aluminum oxide is used. Thesemetal push button switches, when properly sealed, prevent the intrusion of moisture caused by weather, or the flooding of the system caused by inadvertent (or malicious) flooding of the HMI panel. The man-machine interface protection rating is generally up to IP67, which means the metal push button switch is completely dust free and can be immersed in water at a depth of 3 feet for 30 minutes.
Similar to the IP rating scale for entry protection, the IK rating scale defines the level of impact protection. Most damage-resistant switches are rated up to IK10 (currently the highest impact protection rating) with a maximum energy level of 20 jakes.
Many damage resistantmetal push button switches, are set on the button icon, to carry on the function indication; In many cases, LED lights are used to provide operational response in low light conditions.
Metal is waterproof seal and prevent the press of a metal push button switch, it can be 12 mm in diameter of 8 mm / / 16 mm, 19 mm / 22 mm / 25 mm / 30 mm within the body of the standard LED lighting supply. The metal push button switches are made of stainless steel and protected by scratch-proof starter. Rated service life of 500,000 switching operations, suitable for 20°C to +55°C environment. metal push button Switch using single pole double throw and double pole double throw mode, with normally open or normally closed contact, with instant or locking action function.
Stainless steel starter can be selected flat, dome or strip structure, according to the use of the corresponding standard planning. The metal push button switch requires a starting power of 2.5N (SP) or 3.5N (DP) -- a clear pressing action to operate, and can bring a lively tactile response to the user.
The metal push button switch conforms to the requirements of IP67 seal protection, and can withstand the mechanical impact of IK10 grade. Its thread structure can be easily assembled through the front panel, and it can be easily connected with the printed circuit board by using the cross-line function.
