This made me laugh when I found it, because my truck’s brake light switch is jury rigged too, but not quite as bad as this one. I’ll show you mine, and then maybe you’ve got one or two to share with us.
At some point years ago, the brake light switch on the master cylinder went out. I can’t even remember now why I didn’t fix it; maybe it wasn’t in stock, or? Anyway, I grabbed this little universal push-button switch, and secured it to the steering column with a hose clamp. That was about eighteen or twenty years ago. I doubt I’ll ever go back to the real thing now.
