My first thought was the neutral switch but I knew they had a large blob on the end and you deliberately showed them from the other side to throw me off I reckon, does look like the contact plate from the regulator though.

I showed them as they came to be after being made. The blob is a pressed nipple which I have to do by hand  ;) ;)

I've been thinking off having some plates made like those Graham but backing plates the same shape but slightly smaller than the side panel badges for the 500 four, they have a habit of breaking at the bottom of the letter U in the four part as this is the thinnest part of the badge, a plate glued to the back would reinforce this area and allow broken badges to be repaired without risking them snapping again in the exact same place, you think your contact could punch out a card like that one, with say around 30 of the plates on it.

This process is called acid etching and was only worth it because we could get loads on a sheet. Now all I have to do is sell them to cover all the costs  ::)

Nice one  ;) .. may be worth considering fitting a contact rivet like these people sell.

Been on to that company and they don't do rivets small enough for the job  ;)

Such as these may be ok the head will be about 3mm I would think if you want rivets. They do smaller ones as well. https://www.ebay.co.uk/itm/1-16-dia-copper-rivets-1-2-Long-Round-head-solid-rivets-Model-steam-Boiler/283450344078?hash=item41fef5028e:m:myOswG9eYs5mn6yoLtybIdw

I think the originals were rivets with precious metal contacts brazed onto them (like ignition points have). This is the CB250/350K part  # 35752-286-000

CB500 one ( 35752-323-000)  looks like a plain brass or copper rivet from image below. I can't see why you would need precious metal anyway ...it's switching b*gger all current and non-inductive (ie a bulb). In my experience it's the springy metal that fatigues... it's in the crapest position possible on the CB250/350K ..gets blathered with grease and road muck. I guess the CB500 position is similar I guess but can't remember.
