Honeywell's NGC Series Limit Switch Slide 8

There are many applications where limit switches can be used. Switches are used in rail doors and platform screen door applications to sense the position of the door. A signal is sent to the cabin control panel. The train cannot depart if the doors are not in the closed position. Three or four switches are used per train door. Two or three switches are typically used in PSD door applications. Key switch requirements for rail doors are performance, reliability, and long life. The NGC precision snap-action design, and positive-break contacts ensure actuating characteristics over the life of the product. The 5 Million life cycles makes this a good solution for applications with high frequency of operation.
