摘要： A railroad switch stand is provided by which a switchman can easily and conveniently throw a railroad switch while standing, which automatically locks in respective open and thrown positions, and which automatically disconnects from the switch throw rod in the event excessive longitudinal force is applied to the throw rod, the preferred switch stand includes a hand-operable, rotatable throw wheel; means mounting the wheel at about normal chest height; structure for translating rotation of the wheel into longitudinal movement of the rod; and means for releasably locking the wheel in respective, alternate open and thrown positions. In use, a switchman releases the locking means and rotates the throw wheel through one revolution in order to throw the switch to its alternate position at which point the locking means automatically engages the throw wheel to prevent further rotation thereof.
