Well, I will try to answer the best I know:

I'm not sure what you mean by "wear". They are like molded rubber
pushbuttons that have a carbon disk on the back, when you push the button,
the disk makes contact between two gold-plated conductors. Do they wear?

The contact force is someone's finger mashing the button.

The environment is an air-conditioned room full of broadcasting equipment,
so I guess the biggest threat is spilled Diet Pepsi? <grin>

                Jack,
                First questions: Are these areas going to be subjected to
wear?  What is the contact force?  What type of environment?
