Metal Dome Membrane Switch
METAL DOME, Metal dome contacts on the arrays (sheets) are positioned over the contact point of PCBs. When a dome is pressed, the center of it contacts to the PCB and let the electric current flow through.
1) PET glue to do ring test (-35 degree to +75 degree);
2) the stripping force of PET is 0.8kg + 50g.
3) DOME slice test 10% (life 1 million times, surface treatment cleanness and coating, elastic strength + 20g, hand feel 35-60, appearance, travel).
the size of the mechanism hole and the external type (tolerance + 0.15mm), METAL DOME life 1 million times, dirty, pressure wound, fracture, DUBBLE DOME, and lack of timber.
the resistance of CONTACT is less than 3 ohm.
the resistance of EMIL is less than 500 ohm.
the characteristics of:
1) The thinning of the shape is good.
2) The unmistakable operation of the implicit quality
3) Colorization meets individual needs
4) t is easy to distinguish functional keys with good uniformity
5) low power 15mA/LED
6) no noise no long signal
7) Convenient assembly with high qualified rate
8) lower cost and lower cost
9) High security
FORCE and the relationship between the forming height and diameter between the perforations.
The relationship between FORCE and height is determined under the condition of molding material, forming diameter and partition diameter. The diameter is 5 and the diameter of diaphragm is 6. The rest of the data is shown below.
