So I am working on a project where I want a big dumb red button. I got a light-duty industrial illuminated pushbutton from AliExpress (this one, if you want to know: 22mm 3v-6v, non-locking). It looks like it will be fine to use, but I'm confused about the LED. It seems to work regardless of which orientation, and I briefly tried it without a resistor, and that was fine too.

I'd like it to be fairly bright, but as someone who has blown up his share of through-hole diodes in his day, I would rather not mess up this one, since without the diode light it's sad and dumb, rather than glorious and dumb. :-)

My question is this: is there any standard for these illuminated switches that would make it likely that there is some resistor and diode stuff going on inside the housing, such that this thing is fine to just wire up and use?

I am in the process of attempting to install an outside switch for a radon mitigation system. However, I am unable to drill through the remaining part of the block wall. I have an M12 Fuel hammer drill and a carbide drill bit. I imagine something is in the way but what? If it was concrete in the floor I would guess rebar. The first part went through like butter.

One side of my back yard is 6 foot vinyl fence post, then the other side and back are chest high chain link fence that are older than me and have concrete blocks under the ground, so would be a giant pain to remove.

Also I looked up and wires were laid right next to the concrete bases. So I "really" do not want to have to remove them.

The fence was installed before I was born, and the wires laid when I was in elementary school. So don't blame me for the silliness of it please.

Would it work if I just removed the panels from between the chain link posts, then slipped the hollow vinyl posts over them, and connected them with the vinyl panels? I would have to buy different distance panels to make it work, but that seems easier than tearing them out, then digging new holes for the new posts.

Or any other suggestions to make it look nice and not have to try and dig large concrete bases that are next to wires out of the ground?

I have a Nektar keyboard I've repaired for the most part, but the previous owner's bad gluing of the keyboard mechanism wasn't very good.

Since I'm not very good with normal musical keyboards, I was thinking about modifying its keybed into a Jankó keyboard.
