Since you are "making" the circuit, not "breaking" it, much less concern. Or do you need to do both under load?
As long as it is made quickly without bounce, arcing is a minor issue. Breaking a DC circuit on the other hand, you have an arc welder.
Had an old Navy shipboard electrician tell me about WWII ships with a DC system.
Never try to screw/unscrew a lightbulb while under power. Welds itself in the socket!
There is a feature called screenshot in mine where you can capture the screen and paste it in any app, like email or other to print it. You can capture the whole screen or crop just what you want. Right click to see it in the menu.
