Embodiment Construction
[0009] The plane of the four sub-switches 1 is coincident with a surface of the object. If the surface is horizontal, the ball 3 will stop at the root of the two metal terminals. The inner bottom surface of the shell is a slope 5 so this state is relatively stable. When the inclination angle of the plane exceeds a certain value, a ball 3 of the sub switch 1 will slide along the bottom of the inclined surface 5 to the top. Since the length of the two terminals 2 is relatively short, the sub switch 1 is in an off state. At this time, the inductive switch sends a dumping signal to the processing circuit to determine whether the object is falling and the direction of the dumping.

The invention provides an orientation sensing switch. The orientation sensing switch comprises sub-switches distributed in four directions of one plane, the sub-switches change working states through rolling of balls in a housing, the plane where the four sub-switches are disposed is mounted to the surface of an object in an attached mode, and a processing circuit can determine whether the placement position of the object is changed according to the working states of the sub-switches.
Description
Technical field [0001] The invention relates to a direction sensing switch, specifically, a switch that can sense four directions in a plane. Background technique [0002] In the process of dumping some electrical appliances, it is necessary to disconnect the power supply in time. At this time, a reverse induction switch is needed to give a dumping signal to the processing circuit. This dumping signal is represented by the open or closed state of the switch to allow the processing circuit Make an action to disconnect the power supply. The traditional direction sensing switch has a complicated structure and is not suitable for occasions that only need to roughly sense four directions. Summary of the invention [0003] The purpose of the invention is to invent a direction sensing switch that can sense changes in four directions in a plane. [0004] The technical solution adopted by the present invention is that four identical sub-switches are distributed in four directions in a plan...
