Formulation of standards for thin film switches in the electrical industry:
Thin film switch is a multi-layer structure (planar) (non locking) key switch composed of insulating material layers with certain elasticity. Due to its beautiful appearance, long lifespan, and simple structure, it is widely used in various industries, ranging from 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 tape (commonly known as sandwich).
Principle of Thin Film 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 connected instruments (set by the customer) to achieve their corresponding functions.
Requirements for the use of membrane switches
The surface of the installed object should be flat, rust free, and cleaned with alcohol or gasoline before installation.
With the development of the world economy, "quality first" has become a common belief in the international business community, and vigorously conducting research and practice on quality management has become the main means for enterprises in various countries to win in competition. In various domestic enterprises, including the screen printing industry, with the establishment and gradual improvement of the socialist market economy 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 scale for evaluating and measuring product quality or service quality (including work quality, process quality, etc.), and is the basis for enterprises to design and manage product quality.
Without various standards, there is no way to manage; The so-called "standardization", as defined 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 purpose of promoting the best overall economy and taking due account of product use conditions and safety requirements, with the cooperation of all relevant parties, in order to carry out specific activities. The standardization of thin film switches is based on the comprehensive achievements of science, technology, and experiments. It not only lays the current foundation, but also does not determine future development. It is always in line with the pace of development.
The implementation of standardization work, including technical standardization and the implementation of other standards, also needs to be implemented in the quality management process of the enterprise. In this process, standardization and standardization work have been tested through practical work, drawing nourishment from it, continuously developing, and gaining strong vitality. The process of quality management, also known as standardization, is fully utilized in the implementation of quality management.
