As one of the world's leading switch technology suppliers, Lakeview (lakeview-switch) provides multiple series of anti-destructive switches, which can meet different application needs.
The PBM series of lakeview-switch is an anti-destructive sealed push switch, which can provide standard LED lighting in the main body with a diameter of 8mm / 12mm / 16mm / 19mm / 22mm / 25mm / 30mm.
This series of switches are made of stainless steel, and the scratch resistant starter is used to protect the appearance.
The rated service life of the switch is 500000 switching operations, which is suitable for use under the environmental conditions of 20 ℃ ~ + 55 ℃. The switch adopts SPDT and DPDT forms, and is equipped with normally open or normally closed contacts, with instantaneous or locking action function.

Fundamentally speaking, in order to realize the system application, the system needs users to input information to determine the operation they want to achieve, or provide information to the system. Since speech recognition technology is still in the early stage of development, the use of various types of switches is still the preferred method for man-machine interface development.
When technical equipment is deployed in an uncontrolled area and operated by non equipment owners, it is likely to be abused. Individual users sometimes choose to maliciously destroy the equipment for a variety of reasons. Even legitimate users of the equipment may not cherish the equipment. They will press the switch carelessly and vigorously, so as to shorten the service life of equipment, especially technical equipment with man-machine interface. Obviously, for example, a precise membrane based switching matrix is often unable to be used for a long time in the above cases.
As the deployment of such equipment increases, the demand for high-strength man-machine interface also increases. In addition to family life, almost everything we do in our daily life is inseparable from all kinds of push switch control systems.
For example, when you go somewhere by car, you will see that the fuel pump in the gas station is usually equipped with a button to select the gasoline product number. In the case of modern electric vehicles (EV), you will find that the charging station also has several buttons for entering commands and starting / stopping the charging process. Button based HMI equipment is required when inflating tires, cleaning or cleaning our car at the service station.
Even if we travel by train instead of driving, we will see more and more kinds of buttons; When opening the door or using the intercom, for example. When buying tickets, the ticket machine may also be equipped with a rugged man-machine interface.
After arriving at the destination, we may need some cash. At this time, you will find that the ATM is also equipped with a high-strength keyboard to effectively prevent damage. The building we are going to may also be equipped with access control or intercom system. After entering the building, there is also a button in the elevator room to select the floor.
The special switch for high-strength man-machine interface (which can withstand the destructive operation of rough users or malicious saboteurs) is different from the standard switch in terms of manufacturing materials and methods.
Vandal resistant switches are usually made of metal, and stainless steel is the most used, but nickel plated (Ni) brass is also common, and anodic aluminum oxide is sometimes used. After properly sealed, these switches can prevent moisture intrusion caused by weather or water intrusion into the system caused by unintentional (or malicious) water splashing on the HMI panel. The protection level of human-machine interface is usually up to IP67, that is, the switch can be completely free from dust and can be soaked in water for 30 minutes at a depth of 3 feet.
Similar to the IP rating scale for entrance protection, the IK rating scale defines the level of impact protection. The protection level of most anti-destructive switches can reach ik10 (the highest impact protection level at present), and the maximum energy level that can withstand impact can reach 20 joules.
Many anti damage switches are provided with icons on the buttons for function indication; In many cases, operation feedback is provided through LED lamps under weak light conditions.
As one of the world's leading switch technology suppliers, Lakeview (lakeview-switch) provides multiple series of anti-destructive switches, which can meet different application needs.
The PBM series of lakeview-switch is an anti-destructive sealed push switch, which can provide standard LED lighting in the main body with a diameter of 8mm / 12mm / 16mm / 19mm / 22mm / 25mm / 30mm.

The switch adopts SPDT and DPDT forms, and is equipped with normally open or normally closed contacts, with instantaneous or locking action function.
The stainless steel actuator can adopt flat, dome or strip structure, and the corresponding specifications can be designed according to the application. The required starting force of the switch is 2.5n (SP) or 3.5N (DP) - it needs a clear pressing action to operate, and can bring positive tactile feedback to the user.
The switch meets the sealing protection requirements of IP67 and can withstand the mechanical impact of ik10 grade. Its threaded structure can be easily assembled through the front panel. At the same time, the cross line function is used to realize the easy connection with the printed circuit board
