2, product structure: three layer structure, upper paste; RUBBER glue +PET+PET spacer;
3, function: conductive switch key, good feel, good sensitivity.
4, function key life: more than 300 thousand times.
Two, the use of the environment to see the following:
1, temperature and Humidity Cycle Test walk diagram;
2, the product is placed at the temperature: -40℃ --70℃.
Humidity: 10%-93%RH, cycle two times a total of 53H.
Metal dome membrane switch has advantage of long life span, less resistance, stabilization, sensitive action and equal pressure, and has water proof, dustproof, grease proof and other characters.
As an only metal part of metal dome membrane switch, metal dome’s technology specification should match the PCB and the switch assembly, which can enhance the virtue of excellent conductivity, steady return force and superiority tactile when applying in the membrane switch
In order to avoid shortcoming of membrane switch which caused by unreasoning using metal dome only as a tactile part in FPC, here we offer the characters sheet to help customers to choose right metal dome to match membrane switches, which indicates the character of both metal dome and membrane switches, it can farthest enhance practicability of the switches.
