It's hard for anyone else to know how your system is set up. But this is the internet, so I'll just take a wild guess
A push button switch out in the open is probably for an electric head pump. Push the button and waste water exits the bowl while sea water is brought in.
A pull-out switch may be any number of things. On my Prairie there was one for the shower pump. Pull it out and the pump (originally a diaphragm pump) comes on and sucks the water down the drain.
You say there's a macerator. Somewhere there is probably a switch for that, probably not out in the open, but hidden behind a cabinet or something. Unless you're talking about the one that's part of the toilet fixture itself.
As for the hoses, we'd need to know where they terminate. There are lots of ways they could be set up, but two are common:
1) From toilet always to holding tank. From there, a "Y" valve with the option to pump the tank out the through-hull via the macerator, OR via a deck pump-out fitting.
2) From the toilet to a Y valve, with the option to go directly overboard OR to the tank.
But there are other variations. Mine has no Y valve. Toilet goes to tank always, and both macerator and deck pump out are T'd off the tank lower fitting.
