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