Standard Formulation of Membrane Switch in Electrical Industry

Formulation of standards for membrane switches in the electrical industry:

The membrane switch is a multilayer structure (plane) (non lock making) key switch composed of a certain elastic insulating material layer. Because of its beautiful appearance, long life, simple structure and other characteristics, it is widely used in all walks of life, from small household appliances to high-tech products.

The membrane switch is mainly composed of facial mask, facial mask adhesive, upper circuit, isolation layer, lower circuit and adhesive. The structure is as shown in 'membrane switch structure'. The facial mask layer, upper line layer and lower line layer are transparent films, and the main materials used are PC, PET and PVC. The facial mask backing, isolation layer and backing layer are made of double-sided adhesive (commonly known as sandwich).

Principle of membrane switch

When the facial mask layer is not pressed down, the isolation layer will isolate the upper and lower lines. When the facial mask layer is pressed down, the upper lines will be pressed down together and overlapped with the lower lines to make the lines connected. The connected lines will signal the external connecting instruments (set by the customer) to achieve their corresponding functions.

Operating requirements of membrane switch

The surface of the object to be installed shall be flat, rust free, and cleaned by alcohol or gasoline before installation.

With the development of the world economy, 'quality ' has become the common belief of the international business community, and vigorously carrying out the research and practice of quality management has become the main means for enterprises in various countries to win in the competition. In domestic enterprises, including screen printing industry, with the establishment and gradual improvement of the socialist market economic system, the concept of 'quality is the life of enterprises' has been recognized by the business community. When it comes to quality and quality management, of course, standards and standardization are indispensable. The so-called 'standard' is a yardstick for evaluating and measuring product quality or service quality (as well as work quality, process quality, etc.), and is the basis for enterprises to conduct product quality design and product quality management.

Without various standards, there is no way to manage; The so-called 'standardization', according to the definition given by the International Organization for Standardization (ISO), refers to the process of formulating and implementing rules for the benefit of all relevant parties, especially for the promotion of the overall economy of *, with due consideration to the product use conditions and safety requirements, and with the cooperation of all relevant parties, in order to carry out specific activities. The standardization of membrane switches is based on the comprehensive achievements of science, technology and experiment. It not only lays the current foundation, but also does not determine the future development. It is always consistent with the pace of development.

The implementation of standardization, including technical standardization and other standards, also needs to be implemented in the quality management process of the enterprise. In this process, the standards and standardization work have been tested by actual work, drawn nutrition from them, and continuously developed, thus gaining strong vitality. The process of quality management is also the process of standardization, which also plays a full role in the implementation of quality management.
