Washer fluid low level warning

[Sol]

Those float switches are used widely in industry for tank level detection. They need a hole drilled in the side of the tank and when the float hangs down, they detect low water. Turned the other way, full tank detection to stop a pump or close a valve. Not sure how that seller intended a fishkeeper to fit that to a glass tank.....! Also had to be the correct switching action for the application, normally closed or normally open etc.

Aye, all agreed!
