I have a battery that is connected to a light switch (single pole) I also have an inverter and charge controller connected to the same light switch. I want to be able to turn the inverter and charge controller off with the light switch so that it doesn't drain the battery when it is not in use. Can I do this with the one light switch?

Do you have any kind of diagram for this circut and also what are the loads involed as well as voltages.

Is there a reason it HAS to be a single one pole switch? And why would you be using a battery to run a light when there is power available to charge the battery when its in use? And why would you not want it to keep the batter charged when not in use?

What you are trying to do doesn't make sense to me.

Certainly.
