Patent ID: 7159327

Claim:
A touch probe, including a casing that defines a longitudinal geometric axis, a movable arm-set housed in the casing, that defines a longitudinal symmetry axis, an arm rigidly coupled to the movable arm-set, with an end extending out of the casing, a feeler coupled to said end of the arm, and an electric switch adapted for detecting displacements of the movable arm-set with respect to the casing and including a housing, at least one stationary contact, a movable contact, and a mechanical transmission device adapted for transmitting displacements of the movable arm-set to the movable contact, the mechanical transmission device including an elongate mechanical body, located between the movable arm-set and the movable contact, arranged and movable substantially along a longitudinal direction, and guide elements for cooperating with the elongate mechanical body with substantially longitudinal guide surfaces integral with said housing and an elastic thrust element adapted for urging the elongate mechanical body against said guide surfaces.
