I'm working on a device that I hope to sell on a small scale. It involves several panel-mount 3.5mm headphone-type jacks. I'm trying to reduce costs, as it costs quite a bit in off-the-shelf parts to construct one.
As someone who has done lots and lots of prototyping with buttons, switches, etc, I've certainly worked with these types of solder terminals before, using either alligator clips or soldering prototyping wire directly to the terminals. These panel mount jacks in the image below are cheap and I'd like to give the a try. But I've always had it in my mind that there must be better way than simply sticking a wire in the terminal and soldering them together. It seems too fragile to put into something that a potential customer must depend on. In my application these jacks would be mounted to the enclosure and wired to a PCB several inches away.
What's the best way to connect these types of terminals permanently and securely to a circuit?
