Claim 9:
10. A switch device for moving switch rails, the switch device comprising:
a motor operatively coupled to move the switch rails into and between first and second positions, wherein the motor is configured for electricity to flow therethrough along a first path and a second path;
a first path relay having two normally open contacts each within the first path, wherein activating the first path relay closes the two normally open contacts thereof;
a second path relay having two normally open contacts each within the second path, wherein activating the second path relay closes the two normally open contacts thereof; and
a first limit switch activated by movement of the switch rails, wherein the motor stops moving the switch rails when the first limit switch is activated;
wherein 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 wherein the motor moves the switch rails towards the second position when the second path relay is activated and the first path relay is deactivated.
