Your reason is also why Monster Cable can sell $7 speaker wire for $70 because their wire also has polarity.
Your knowledge comes from observation without the other "always required" underlying theory and education. I also know a physicist. Therefore I completely understand Einstein's Theory of Relativity? That was your reasoning.
Switches have no polarity as others have said. I will add another perspective - some engineering knowledge. We routinely short digital inputs or outputs and cause no damage to digital semiconductors. A technique to analyze failures and locate defects: short or power digital circuits in violation of what the drivers were trying to output - intentionally create change - and never damage digital electronics.
Your switches are connected to the same devices. Short them out or short them to a 5 volt supply and not cause damage. Or you could do what the switch does between two points - connect a wire between those two points - and not damage anything.
This post only confirms what others have said using EE knowledge. I have serious doubts about your 'engineering' source. Either they have no engineering knowledge, or (more likely) you did not grasp what they said.
Nothing about those switches can harm semiconductors. More likely: you did not use a static protection wrist strap. Therefore zapped semiconductors with destructive 10,000 volts - and did not realize it.
Meanwhile, reverse voltage on an LED can harm the LED. LED may be powered by 5 volts. But the same LED is only good for a reverse voltage of maybe less than 3.75. That damaged LED may still light. But overstress causes failure at a later date. Possible? Yes. Likely? No. But once I add knowledge you did not have, suddenly your "reverse connected LED" observation was a classic 'junk science' conclusion.
Your conclusion was based only in observation without the benefit of basic electrical knowledge. Once that engineering knowledge was added, then your conclusion completely changes.
Junk science is a conclusion only from observation - without first learning the underlying electrical principles. Junk science is also why Monster Cable sells wires (like your switches) with polarity for a massive 10 times higher price.
