| 1. An apparatus for detecting an electronic product being placed vertically or horizontally, comprising:
a constraint base;
a fixed support member connected to said constraint base at an anchor point and extending upwardly from said constraint base;
a cantilever having a first end connected to said fixed support member so as to dispose said cantilever to be approximately
parallel with said constraint base and a second end opposite to said first end;
a counterweight mounted on said second end of said cantilever in order to provide a force thereof, said counterweight defining
a gravity line by virtue of ground gravity; and
a sensing device for converting bending of said cantilever into a circuitry status;
wherein, when said cantilever extend in a direction approximately perpendicular to the gravity line, said sensing device converts
the distortion of said cantilever into a first circuitry status, and when said cantilever extends in a direction approximately
parallel to the gravity line, said sensing device converts the distortion of said cantilever into a second circuitry status
different from said first circuitry status.
