Audio Jack Safety 230v DC
This should absolutely not be used above ~20-30 volts, and even that's pushing it.
One of the main problems with T(R*)S connectors is that, when inserting or removing the plug, the contacts are briefly shorted together. This isn't much of a problem in audio, but for power applications that means shorting the power supply, and for high voltage sources you can get huge current spikes during the short.
And even if you had a workaround for that, these aren't insulated properly for that kind of voltage. You can just touch bare metal on them, and that's not good when that bare metal could be at 230 V with respect to ground!
More appropriate for this task would be something along the lines of solar panel connectors, designed for this kind of voltage. Notice how they're large, and insulated all around, so you can't touch bare metal anywhere on them. Some fully insulated banana plugs are also suitable for this purpose, but do make sure you know what you're doing when terminating them.
