    摘要： A switch device for moving switch rails. The switch device includes a motor operatively coupled to move the switch rails into and between first and second positions. The motor is configured for electricity to flow therethrough along a first path and a second path. A first path relay has two normally open contacts each within the first path, where activating the first path relay closes the two normally open contacts thereof. A second path relay has two normally open contacts each within the second path, where activating the second path relay closes the two normally open contacts thereof. The motor moves the switch rails towards the first position when the first path relay is activated and the second path relay is deactivated, and the motor moves the switch rails towards the second position when the second path relay is activated and the first path relay is deactivated.

    摘要： A vital proximity detection mechanism and method for reliably determining and communicating the position of a railroad switch point relative to a normal fixed track and a reverse fixed track, wherein the mechanism includes substantial component redundancy and fault-checking features and otherwise meets promulgated safety standards for vital componentry. The mechanism includes an RF transmitter and remote status indicator unit to allow for remote adjustments of proximity sensors while monitoring the effects of such adjustments.
