Patent ID: 8319124

Claim:
An electric switch apparatus used in turning off and on at least one electrical circuit connected to said switch based on water level inside the apparatus from falling rain, the electric switch apparatus comprising: a container having a top cover with at least one opening receiving falling rain and an interior collecting said falling rain with a water level indicating amount of water collected inside said container; a first electrically conductive member; means to attach said first electrically conductive member to said container; a second electrically conductive member positioned above and facing said first electrically conductive member and making direct physical contact with said first electrically conductive member to form an electrical connection when said second electrically conductive member comes down on said first electrically conductive member from above; a floating body placed inside said container and floating in said water and to rise and fall freely along with the rise and fall of said water level inside said interior of said container; means to attach said second electrically conductive member to said floating body such that said second electrically conductive member and said floating body move together; said floating body resting freely inside said container in absence of said water causing said second electrically conductive member to fall on top of said first electrically conductive member to physically and electrically engage said first electrically conductive member to form an electrical connection between said first electrically conductive member and said second electrically conductive member to turn on said electrical circuit; and said first electrically conductive member and said second electrically conductive member being physically and electrically disengaged and disconnected to turn off said electrical circuit when said floating body is afloat in the presence of said water inside said container.
