Abstract:
A device for switching an electrical signal as a function of wind speed, comprising:a wind vane;a shaft attached to the wind vane such that the wind acting on the wind vane causes the shaft to rotate in a first rotational direction, the shaft having a first, a second, a third, and a fourth shaft position;an electrical switch having a first and a second switch position;an actuation unit having an actuation unit biasing element, the actuation unit configured to engage the shaft and the electrical switch, the actuation unit biasing element configured to supply a first actuation resistance to shaft rotation at the first shaft position, and the actuation unit configured to switch the electrical switch from the first to the second switch position at the second shaft position; anda reset unit having a reset biasing element, the reset unit configured to engage the shaft, and the reset unit biasing element configured to supply a first reset resistance to shaft rotation at the third shaft position and to supply a continuous resistance to the rotation of the shaft when the shaft rotates in the first rotational direction from the third to the fourth shaft position.
