I have had some loose switches for a while.

Yes. I spent good parts of my childhood on Apple II clones with reed switch keyboards.

You should do a wiki on them so I can copypasta it.

Check these:

Edit: Oh wait. Those don't look like magnetic reed switches to me.

I don't think those were magnetic either.

R.I.P. Steve Jobs
I was general manager at Datanetics in Fountain Valley, Southern California. We built keyboards for cash registers and desktop calculators. IT&T bought the company around 1976. Steve Jobs dropped by on the way back from New York and asked me to build keyboards for the Apple II. By the spring of 1977 we were in full production.

In early 1978, Datanetics built keyboards for Mattel and others which prompted Steve's suggestion that I start a new company dedicated to supply Apple's needs.

Well, I guess not then...

I've come across some "Ghetto" Magnetic Reed Switches:

Tec is a terrible name...anyone have any info on them? Info will be rewarded with more pics :D.
Harris is the company that distributed the keyboards.

I have 2 of these boards, 1 that's complete, the other is missing keys. Both of them lack controllers, but have speakers. The reed switches still work.

IIRC, the one I used had the reed switch vertically mounted.
I could still have one in possession in a remote location, or available in friend's collection.

IIRC, boring linear. But the subtle reed click was pleasant.

I am a commie. It was a locally produced keyboard (early 1980s), so it might as well be local design/clone.
Since getting access to mine could take close to a year, I will ask a friend to search his collection.

It could have been like this:

Human memory fades faster than magnetic media. Sorry for not being more specific.

What I found interesting, is that the above locking switch is very similar to the "Made in Mexico" reed switches I have, down to the pointing arrows.

*See first post*
