Michael - for the 4553 specification, we tested IAg used with a soft touch
membrane switch for 1000,000 cycles with no problems. The test was run over
a prolonged period which allowed for the surface to tarnish but the results
remained excellent. The data can be found in the appendix of the spec. We
did not allow IAg to be used as a switch surface to be used for class 3
applications however.

Has anyone successfully used the IAG surface finish for keypad contacts
instead of gold?
Thank you.
