Hi Ecumaster Community,

its some sort of a dummy question, but i couldn’t find any information here in the forum nor somewhere else.

I’ve got a simple on/off switch i want to use as a map switch. So i have to connect one cable to one of the switch inputs, right? The other cable goes to the 5V supply? Or 12V?

Best regards,

Lorenz
