Triangle shape metal dome Specification :
1).common material:SUS301、 SUS304
2).Surface treatment: nickel plating, silver plating, gold plating
4.) Commonly used strength: 130g-350g
5). Contact resistance: gold-plated <silver-plated <nickel-plated <stainless steel <1Ω
6) .Storage temperature: -40 ℃-85 ℃
7). Life test: more than 100,000 times
8).Shrapnel vertex: no vertex, 1 vertex
There are two kinds of triangular shrapnel: with and without legs.
According to the thickness of the PCB board, you can choose the appropriate leg-length shrapnel, and insert the shrapnel with the foot directly into the PCB board with holes,which saves the process of welding and gluing.
