Micro Switch SD collar

[MMcM]

I have been working on a board with SD switches. A half dozen of the switches don't operate. This is because someone has installed some sort of inhibitor on them.

A bit of plastic wraps around the plunger and inserts in a way that prevents it going into the switch itself.

They are relatively easy to remove and so obviously intended to be temporary / configurable.

Most of the switches that have them also have blank caps. But not all, so it was installed for known functionality of the system that some station wasn't allowed to use.

Has anyone else ever seen these? Do they have a real name in price lists or other literature?

Normally the keys could work like other working keys when you remove the, emm, lock. Surely the sensors are not different with others as well.

At least that's what I found on my SD board, I did find one.

I've never seen these before. Cool find What board did you find these in or would that be too much of a spoiler for the time being? Reminds me of the collars I found for Alps switches.

There are similar easily removable blockers under some caps of the Raptor K1 (which is a special edition of the Cherry G80-1800):

Wew... impaled... that's quite a design. I haven't seen them personally, but that's interesting.
