摘要： A railroad switch indicator, that operates independently of the mechanism for operating the switch, for signaling the position of the switchpoints via a flexible mechanical cable connected to a railroad switch amplifier mechanism. The railroad switch amplifier mechanism has linkage members attached to a crossbar connecting inner stockrails and to a pivoted lever arm, the output arm of which is attached to the mechanical cable. The flexible mechanical cable allows the railroad switch indicator to be positioned remotely from the switchpoints and switch amplifier mechanism in a highly visible and easily serviced location.
