ETA Rocker Switch

[Pinecone]

I know that there used to be a 3D print model for the rocker part of the ETA switches, but it seems to have been removed.

I have a friend (also pilot) who is big into 3D printing.  If I can get him an undamaged one, he will model it and either supply them or supply the print file.

AFAIK, the template will be returned unharmed.

Thanks.

Or maybe a full set of replacement of switch covers in the donators color of choice?

And these are for the newer ETA switch covers, correct?  If you're looking for the Klixon switch cover, @AH-1 Cobra Pilot is (was?) making them.

Following...have a 3D printer, but no model.   I did buy a 3D printed switch in the past, but it didn't fit...looked right, but might have been to hard of a plastic to snap in.

[Pinecone]

I may be able to work the set for the person donating. 

Yes, newer ETA switches.

In the long thread they pointed to a site that prints and sells 3D printed items, but the page for the ETA switch is no longer up.

Yes, I still make the Klixon switch covers.  I do not have a CAD file for the ETA switch covers, nor do I have a cover, so I have never made any of those.

For the ones I make, the post-processing is a big deal, much more than just the printing.  I paint them, then laser engrave the lettering.

Right now, I am printing something new and will have pictures posted soon.

That is why I am trying to get a good (not broken) ETA switch cover, it get a CAD file done, so we have a source for them.

But no one seems to have a spare one to donate for a short period.

There are usually some for sale on eBay.

Also check with your mechanic.  I know mine has a box of random switches and switch caps. 

I probably won't be back over there until Jan.  But if you're still looking after the holidays, shoot me a reminder and I'll ask him.

 

[Pinecone]

My mechanic should have seen this.

I bought some of those ETA switch covers from Shapeways and I still have a couple left.  They do fit perfectly on the switches.  I can send you one if you need?

I wish I knew something about CAD, I keep trying to learn it, but whenever I start my brain explodes and I wake up a few hours later

That would be GREAT.

I will DM my address.

What year (and what models) did they switch from Klixon to E-T-A?

I don’t know. My 1978 M20J had Klixons, and my 1994 M20J has E-T-As.

[jetdriven]

1984s had ETA. 1980 have Klixon.  So somewhere in there.

Myrtle is presently getting a complete panel upgrade. We are replacing all the switches. I will be happy to provide you with what you are looking for if I have it. Myrtle is a 1982 K model.

Shapeways has klixon covers. Worth trying for the price.  https://www.shapeways.com/product/7PX88KE24/switch-cover-klixon-20tc-v0-6-textured-front?optionId=56024562

Thanks.  You do have ETA?
 

One is on it way to be models, but is needed, I will reach out for another one.

Are you putting rockers back in?  I have been thinking about going to toggle switches when I do a panel upgrade.

Just remember that those are circuit breaker switches, so you need to either find a different breaker/switch or install breakers with the new switches.

We are planning on putting toggle switches back in their place...and yes breakers.

Yes, but thanks for the reminder.

 

Do they make toggle switch breakers?  Or would you need to put in separate breakers?

Great, I would love a picture when you are done.   I was thinking about how to label them, but with lighting.

Someone must make them — It seems pretty common for Cessnas to have one for an avionics master. 

[Pinecone]

Here they are.  Used in Beech, Cessna, and Piper aircraft.  0.5 to 50 amp rating.  But only down to 1 amp listed.

I'm a 1989 M20K so that almost certainly means ETA.  Can you tell from the pilot side of the panel?

[AH-1 Cobra Pilot]

I tried printing switch covers in Glo-in-the-Dark ABS filament.  They printed well, but the glow is too weak.  I also printed some in PLA, which has much better glow, but will not survive cockpit summer heat adequately.

I also just discovered I cannot post photos, since my attachments are at 137%, whatever that means. ???
