10 electrical parameters of membrane switch keyboard

1,Configuration--momentary SPST normally open
2,Current Rating--30V-100MA to 12V-10MA maximum
3,Breakdown--220V RMS
4,Closed--100 OHMS typical contact resistance
5,Open--10 MEG OHMS contact resistance minimum
6,Capacitance--30 Picofarads
7,LED Rated voltage--1.9-3.2V maximum
8,Membrane keypads Life
a,Flat switch keypad--approximately 5 million cycles
b,Domed(embossed)layer--approximately 5 million cycles
c,Domed circuit--approximately 1 million cycles
d,Matel dome--approximately 1 million cycles
9,Contacts--silver to silver.General label only uses high-quality silver,Low quality silver may not last as long and may contribute to silver migration(the tendency of silver to spread or "creep"especially when exposed to moisture)
