So you're trying to make it foolproof. That's not going to work in the long run, but you can try. Put two momentary switches (normally open) in series with the jack. Place the two switches far enough apart that they cannot be operated with one hand. Then the operator will need to insert the probe and let go in order to operate both switches. "It is difficult to make things foolproof, since fools can be so very clever." | |

| Jul 24, 2018 at 17:14 | comment | added | evildemonic | Can you have it go through a GFCI outlet first, for safety? | |
| Jul 24, 2018 at 17:14 | comment | added | DIODEX | it is part of a panel fixture. It is not something just laying around. So it is enclosed all the way around except for the measuring points at the 2mm banana jacks | |

| Jul 24, 2018 at 16:40 | comment | added | DIODEX | The jacks I am adding in are 2mm jacks meant to be inserted with the leads of a DMM. So there is not really a standard banana jack that you can install. | |
