Triple Pole

The inspector says that the indoor portion of the mini-split heating and air con unit has to have a switch to be able to turn the unit off and that it has to be a 3 pole switch. It has 208-230 volts.

So I bought a switch with 9 projections. I assume the out side is where the white, red and black wires go with the ground going in the middle.

I have three questions: Do the wires get soldered to these square projectiles with a small hole in the middle or how do they get fastened? What protects them one from another? And there are three middle projections which I wonder: Are they for the two ground wires.

Is there a U-tube picture of how to do this?

Is this 3 phase power?

Assuming white is neutral, neutral and ground are never switched. They should not be connected to a switch. Oh wait are you talking about the 24 volt control voltage?

So I bought a switch with 9 projections.
A on/off 3pole switch would have 6 terminals.

Your post is very confusing. Can you try again with more details?

Question

Adding to Ray's questions, is this a residential or commercial application?

What is the make and model of your switch? Can you post a picture of it? (See How To Include Pictures) How many wires are coming from the panel to this switch, and what color are they?

It sounds like you have a solder-lug switch, similar to what you might buy at Radio Shack. You need something more like this:

60 Amp 2 Pole AC Disconnect, Molded Case Switch Type NEMA 3R-DPB222RP at The Home Depot

This one is only a 2-pole disconnect, but they have similar 3-pole devices.

If it's running 240v, you only need a 2-pole disconnect (Hot/Hot). If you're actually running 208/3-phase, you do need a 3-pole disconnect... but you're probably in a place that you shouldn't be doing the wiring yourself. The neutral and ground never get switched.
