So that you will understand what I meant, the switches will not have
to operate in space, under the ocean's surface, immersed in harsh
chemicals or substances, or temperatures below or above what humans
consider comfortable.


Will it be in a vacuum? If not, you have a lot of arcing & surface
oxidation that will degrade the contacts. Real switches use some type
of contact lube to keep oxygen away from the contacts. Also, you never
want any silicon based lube on switch contacts. The phone companies
learned that the hard way.

What, other than "don't" was the lesson?

Go not to the Net for answers, for it will tell you Yes and no. And
you are a bloody fool, only an ignorant cretin would even ask the
question, forty two, 47, the second door, and how many blonde lawyers
does it take to change a lightbulb.
