Brake Light Switch, 1937 120

My brake light switch failed due to a loose terminal. I found one that will fit locally. (Standard brand)

When I went to install it, I found the box had a slip of paper inside advising that "This part is not certified for use with silicone fluid".
I'm pretty sure my car has DOT 5 fluid in it. Has anyone had any issues with typical brake light switches and DOT 5 or other modern fluids? The replacement switch does not appear to be very old. That type switch will fit a very wide range of older vehicles and some fairly late model HD motorcycles.
