Four legged shape metal dome specification

Four legged shape metal dome specification :
1).Common material:SUS301、SUS304
2).Surface treatment: nickel plating, silver plating, gold plating
3).Common diameter:5mm-20mm
4).Commonly used strength: 130g-400g
5).Contact resistance: gold-plated 6).Storage temperature: -40 ℃-85 ℃
7).Life test: more than 100,000 times
8).Shrapnel vertex: no vertex, 1 vertex
9).The working principle of the Four legged shape metal dome is that the dome at the top of the dome is the main interface, and the four feet extending outward are used as the support. When the main interface is under pressure from the operator, the dome in the center of the main interface contacts the PAD on the line, and then The feet form a loop again, which results in conduction.
