Horn button replacement for Honda 1996 - 2000 Civic, CRV

EDIT: I installed these and they lasted like 3 days in the summer, i will revisit this, but for now I'm just leaving the key caps off as they still work without, just not very pretty...

This generation of plastic horn buttons is getting to the point where many cars I've seen, including my own, have cracked and exploded horn buttons. What is worse, 3rd party replacements don't exist. My local scrapyard wanted $18 EACH from a donor car, which that plastic was just as brittle.

With this kit, you can make new ones from a couple of 50¢ switches and pennies of plastic.

What you'll need:

What's left of the existing horn buttons (primarily the button face, if you want to preserve the OEM look)

Some short wire (I'm using 24 gauge)

Terminal connectors in multiple sizes

Some 2-part epoxy adhesive

PTFE Super Lube or something similar

PETG filament (probably could use better, but this is all I have on hand)

2x MX switches (I'm using some cheap Outemu Blues; tactile feels better for this application)

Instructions:

Step 1. Harvest the button faces and use a Dremel to clean out the old stem and prep them for epoxy, as seen in Photo 4.

Step 2. Use the epoxy to glue the appropriate new MX stem onto each faceplate. Let cure.

Step 3. Solder the wires to your switches and shrink-wrap them. (Before soldering, it might be smart to check if your switch fits into the socket, as my printer's tolerances might be different than yours. To remove, use a screwdriver and press on the center pin of the switch.) See photo 5.

Step 4. Feed wires through the appropriate holes and VERY lightly lube the alignment pins with some PTFE Super Lube or similar.

Step 5. Crimp on the terminals and install like the originals would.

DISCLAIMER: Removing or tampering with a vehicle's airbag carries inherent risks of accidental deployment, severe personal injury, or property damage. Additionally, installing aftermarket switches or non-OEM components may lead to electrical failure, safety hazards, or failure to pass official state or local vehicle safety inspections. Proceed entirely at your own risk; no liability or responsibility is assumed for any damages, injuries, or inspection failures resulting from following this guide.

PS:  I will not make any adjustments to the model in the future because this was my first FreeCAD model and I am SO done with this project LOL
