Solar Panel Led Circuits
How do I wire a switch to a voltmeter to read six separate circuits?
I have 5-6 power sources, a combination of generators, batteries and solar panels.
I purchased a voltmeter on ebay that will allow me to check the voltage on each of the power sources:

Facts:
I know I can hook this up to each of the circuits and get a reading.
I do not want to rewire every time I need to get a status of each of these circuits.
I do not want to have six readouts.
I want to be able to flip a (perhaps a rotary switch) to see the condition/voltage of each of the 5-6 circuits. Does that mean I need I need a six pole switch? If you know of a specific product that will do this please include a detailed product description.
If your 6 sources do not have a common negative, you had better take Goober’s advice and use a 2- pole, 6- position rotary switch.
If the negative of each supply is common, you can use a single pole switch, and you only need run the negative meter connection to the common negative, and wire each positive to a separate switch lug. Then connect the meter positive to the common (wiper) terminal of the switch.
Beware, the switch type for either method must have “non- shorting” type contacts!
