Synchronous Switch

I'm trying to use a digital voltmeter to display the value of two separate power supplies and would like to use a physical switch to alternate between the two. (see attachment)
Does such switch exists ?

Found my own answer, and in case someone is looking for that as well it is a TPDT (aka 3PDT) switch

Volt meter with 3 connections? Is it a panel meter?

Also, do the two supplies need to stay separated? Otherwise you can make them share a ground. That way you only need a single pole switch.

TPDT RELAY
3-pole DOuble throw

Yes it's a panel meter and it also measure the current, hence the 3rd wire. Good point on the shared ground. Thanks!
