Is this a normally open switch?

The float switch is normally open when the float/water level is down.

can this be used for well s?

Yes, it is activated when the water level lifts the float up on its side causing the contacts inside the unit to connect causing the power to the pump to be activated. As the water level drops the contacts separate cutting the electricity. You set the float to activate by the length of the cord to water level.

does anyone know what I can use to send me an alarm when the switch is closed?
