I have a CC/CV DC to DC converter I bought on aliexpress.
I does not come with a screen so I attached to it an LED voltmeter ammeter.
Anyway everything works fine.
One thing though, I don't know at what value the CC potentiometer is at. To adjust before attaching a load, I short the output and the ammeter gives me the Amps the CC is at. So I can adjust it.
My question is. I want to add a push button which would short the output so I can see the CC value. A pushbutton normally open.
Would that cause problem if there's a load currently attached to the output as well. I'm thinking about sparks and bounces and voltage spikes.
I am a software engineer just tinkering with electronics.
