摘要： A ferromagnetic ball (1) is mounted between dished first and second contacts 2 and 5 and subjected to magnetic restraint tending to retain the ball 1 in its central, rest position by means of a rare earth type magnet 7 which is accurately positioned relative to the ball 1 by means of a polyester shim 6 clamped between the first contact 2 and the magnet 7 as a result of resilient deformation of an annular portion 9 of a cap 8 attached to a housing member 11 enclosing the first and second contacts 2 and 5. Lugs 18 extending from the first and second contacts 2 and 5 pass through openings in the housing member 11 and through apertures in a printed circuit board 16 to which the sensor is attached by dowels 19. The lugs 18 are then attached to the printed circuit board 16 by soldering.
