Just wondering what voltage should limit switches, home switches and e-stops should be?

The voltage should be compatible with your input card. Normally 5, 12, or 24 volts depending on the board you are using.

Thank you.

Thank you.

I also have a S-350-36 power supply. It has a option of selecting either 110v or 220v. I have both available. Why would i pick one source over the other?

Strictly speaking from an electrical perspective, a higher voltage allows you to run at a lower amperage. So a 110V 20A piece of equipment wired to 220V could run at 10A. Less current/amperage means you can use smaller gauge wire though that depends on length. Your equipment determines how much power you need. Length determines size of wire based on current/amperage needed. Breaker is sized to protect the wire.

Regarding your situation, it really depends on your equipment. But generally speaking, if you have access to 220V and your equipment will work with it, I’d definitely use 220V.
