主权项

1- A device (100) for the indication of engagement of gears in a two wheeler said device comprising:
(i) a housing (5) provided with a central disc (50) having a substantially symmetrical, integral, arcuate peripheral flange (55) defining a central cylindrical cavity; said central disc (50) provided with at least one spaced out locating element (60) and at least one projection (70); said locating element defining a locating surface (65); (ii) an integrated circuit board member (10) provided with a central cutout (75) defining a perpendicular axis (Ax), and openings (80 and 85); said electronic circuit provided with at least one sensor (90) and components adapted to sense variation in magnetic flux density, generate and transmit such signals; in an assembled configuration of the board member (10) and the housing (5), said locating element (60) and projection (70) adapted so as to engage said openings (80 and 85) respectively in a pre-configured orientation; (iii) a movable element (82) adapted to be angularly displaced with reference to said perpendicular axis (Ax); and (iv) a sealing plug element (20) adapted to rigidly mount said board member (10) on said locating surface (65) so as to maintain uniform air gap between said movable element (82) and sensor (90) in said pre-configured orientation.
