Do all bilge pumps have a float switch?

No, not every bilge pump is integrated with a float switch. Primarily, only the automatic bilge pumps are the ones that are integrated with a float switch that you can make the most use out of. However, you can buy a float switch separately if you have a mechanical bilge pump in your boat.

You can wire most float switches directly to the battery you have for power. Then you can connect it to your bilge pump. This can be done with the wiring that has been provided (or should be in any case).  After that, when the water levels reach the depth to turn on the float valve it will work automatically. Alternatively, you can turn on the bilge pump using the switch on your dash. It works either way.
