Abstract
Abstract A frame member having two side walls and two end walls surround a cavity, and a cylindrical member is supported for pivoting in the cavity of the frame member. A magnet is mounted on a side of the cylindrical member, and at least one magnetic switch is mounted on a side wall of the frame adjacent to the magnet. When the cylindrical member pivots beyond the predetermined angle, the magnetic switch will be actuated.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
85 words
A wind alarm sensor comprising: a frame member; a pivoting member supported for pivoting motion in said frame member; magnetic means for maintaining said pivoting member in an erect condition when said wind is less than a predetermined velocity; switch means; wherein, when the velocity of said wind is below a predetermined level, said magnetic means will maintain said pivoting member erect; and when said wind velocity exceeds said predetermined level, said wind will cause said pivoting member to pivot to thereby actuate said switch.
