  • Tactile pin actuator
    Patent number: 10446058
    Abstract: A tactile pin actuator comprises a tactile pin assembly that includes a tactile pin and a recess that has a first screw thread formed thereon. A stop assembly is rigidly coupled relative to the tactile pin actuator. A lead screw attached to a shaft is positioned in the recess and is mechanically engaged with the first screw thread. A projection extends axially from the shaft. Rotation of the shaft in a first rotational direction relative to the tactile pin assembly causes the tactile pin assembly to move linearly in a first linear direction away from the shaft. Rotation of the shaft in the first rotational direction ceases when the projection comes into contact with the stop assembly. Rotation of the shaft in a second rotational direction causes the tactile pin assembly to move linearly in a second direction toward the shaft. Rotation of the shaft in the second direction ceases when the projection comes into contact with the stop assembly.
