[sdiy] Gold plated switches vs other types of plating

[Karl Ekdahl]

Ah, yes i have been looking at the number of toggles as my first clue. However to compare two switches i took them apart, and while they seemed pretty much identical inside i noticed that the inside "flip blocks" were gold plated on one and that made me curious as to how big of an advantage that would give over the other switch.

Karl,

I think that I would start with the switches data sheet. One of the specs
should be the number of toggles. If it's not then maybe it's not that great
of a switch. Thinking about it it may not gain you any switch toggles but
offer a switch with less contact resistence. In higher current applications
this could translate into number of toggles but in low current cases I don't
think it would.

Good luck.

Hi list, i've been wondering about switch plating lately - while i
understand that switches that have an internal gold plating is going to last
longer than nickel plated ones, i'm wondering just how much longer? Is it
time while used or unused (as in time to make build-up happen)? And what
coating are switches generally that are not gold plated, is it nickel?
What's the life expectancy of those? Confused..

Thanks!

Karl
