Abstract
An electronic sensor for a quick release mechanism in a railcar vertical hand brake having a housing equipped with a flexible clamp mounted on an inside wall, and a release shaft having a member disposed perpendicular to and about the circumference thereof. A first element is disposed on the member and interposes with the flexible clamp when the release shaft is rotated to achieve and maintain a full brake release. A second element engages a projection on a ratchet wheel when the operating shaft is rotated to disengage the first element from the flexible clamp. A sensing device is disposed in a predetermined position for detecting when the release shaft is rotated into a release position, and for communicating a signal, indicating that the hand brake is in the release position. A device for activating the sensing device when the release shaft is rotated is disposed in a predetermined position.
