Oblong shape metal dome specification ：
1）.Common material:SUS301、SUS304
2）.Surface treatment: nickel plating, silver plating, gold plating
3）.Common diameter:4mm,5 mm
4).Commonly used strength: 130g-350g
5).Touch :35-65%
6).Contact resistance: gold-plated <silver-plated <nickel-plated <stainless steel <1Ω
7).Storage temperature: -40 ℃-85 ℃
8). Life test: more than 500,000 times
9). Shrapnel vertex: no vertex, 1 vertex, 3 vertices, 4 vertices, 5 vertices.
The vertex is a notch above the shrapnel.Generally, shrapnel with a point of contact is better.
