How to Choose a Float Switch for Your Water Pump
Quick answer

Match the switch to your supply (usually 220V) and make sure its current rating is higher than your pump's, otherwise it will burn out. Small domestic pumps may work with a 4A switch; larger pumps need a contactor. Check the cable reaches the tank and the float moves freely, then test by lifting the float by hand.
