Electric switch and position sensor thereof

An electric switch applied in an electric appliance having an electric motor, the electric switch comprising:

• a circuit board located in a switch housing of the electric switch, a conducting path for clockwise rotation of the electric motor and a conducting path for counterclockwise rotation of the electric motor arranged on the circuit board;
• a changeover device configured to movably contact one of the conducting paths for changing the rotation direction of the electric motor according operated from outside;
• the changeover device comprising a position sensor, wherein the position sensor comprises a disk, at least two spring arms and corresponding haptic elements, the at least two spring arms are arranged on one plane surface of the disk independent of each other in structure, first ends of the at least two spring arms respectively fixed on the disk and second ends of the at least two spring arms being free ends;
• the first ends of the at least two spring arms are respectively located at positions which are separated from each other at substantially 180° according to a center point of the disk;
• the haptic elements are provided on the free end of the at least two spring arms respectively and the haptic elements configured to provide individual rotational positions of the position sensor with tactile feedback;
• wherein the tactile feedback is produced by the haptic elements forced against with the housing by a spring force of the at least two spring arms;
• wherein the individual rotational position of the position sensor is different when the changeover device is connected to different conducting paths.
