摘要 A railroad switch stand is provided for operating a railroad switch between two positions. The switch stand comprises a connecting rod connected to an operating mechanism for causing reciprocation of the connecting rod, and a handle connected to the operating mechanism for pivotal movement about a pivot axis between two operative positions. The handle has an open framework having an external configuration which is generally triangular in shape, with the apex of the triangle disposed at the inner end of the handle part where it is connected to a stub portion of the handle. With this configuration, the outer end of the handle presents a portion extending upwardly which can be easily grasped by a railroad personnel when it is desired to throw a switch.
