Metal Dome Switch

Advantages: agile operation, fast assembly, disadvantages: bad experience for customers, no dustproof function, easy to be invaded by dust, and cause contact problems. Therefore, the single-layer pot-shaped pieces are becoming smaller and smaller in the market. Only when the Tiebei sealed machine does not require the protection and operation of the pot-shaped pieces, the whole-plate stickers and single-layer structured pot-shaped pieces will be used. The advantages of Double-layer film potstickers are: dustproof, durable, good feel, etc.

Disadvantages: high cost, slow assembly, etc. Double-layer membranes are widely circulated in the market, and almost all electronic products use double-layer structure pots, such as gaming keyboards, medical equipment, and even as small as remote controls. The single-layer metal dome picture below: The application of Guozi films and Guozi film stickers are becoming more and more widespread, and currently involves all aspects of life, such as the induction cooker we use for cooking, TV, air conditioning remote control, mobile phone equipment, bank U shield, cash machine, medical equipment products, various A series of buttons, touch switches, and other products are used in the pot.

Metal dome switch: the part to complete the work on the pan film switch

Metal dome is widely used. The metal dome is also the most important part to complete the work on the membrane switch. The main function of the metal dome is to contact and disconnect the power supply. Metal dome is generally made of SUS301 or 304 material. The life of the metal dome is generally over 100,000 times. The strength is determined by demand. Do not use it under too high temperature. Excessive temperature will seriously affect the service life of the metal dome.The metal dome is used on the membrane switch to play a conductive role, conducting the two-pole contact of the membrane switch and rebounding by its own elastic force to complete the power-on and power-off functions. It is energized when the shrapnel is down and powered off when the shrapnel rebounds. Give the customer tactile feedback during the rebound process, with a certain feel (Note: proper operation, excessive back and forth movement may cause the switch to lose response).
