Electricity help please?

This is a not a good way to do this.

First you better make sure your float switches are rated for 110vac, the little cheap ones usually aren't.

Second, if your switches aren't sealed at the top you may want to think about this a bit, get them wet or submerged and you are going to electrify the tank.

It would be a far better idea to use a 12vdc circuit for the switches and use that to flip 110vac on the relay.
