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.
Claims2
A wind alarm sensor comprising:
- a frame member;
- a pivoting member supported for pivoting motion in said frame member;

- 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.
