LightRail Switch Stop Kit for LightRail 3.5/4.0, pack of 6

Replace Worn or Missing Switch Stops, Pack of 6

A light mover that overruns the end of its rail or reverses inconsistently usually isn't broken so much as missing the small parts that tell it when to stop and reverse. This kit replaces occasional missing or worn switch stops on LightRail 3.0, 3.5, and 4.0 systems, restoring the stop-and-reverse function that keeps a light mover cycling smoothly across its rail.

Each kit includes 3 pairs of switch stops along with the thumb screws and slide nuts needed to mount them, packaged in a compact ziplock bag so spares stay organized between uses.

Key Features & Benefits

• 3 Pairs of Switch Stops — enough to replace stops at both ends of a rail, with spares on hand.
• 6 Thumb Screws Included — hand-tighten without tools for quick installation.
• 6 Slide Nuts Included — secure each switch stop firmly to the rail track.
• Compact 4 x 4 Inch Ziplock — keeps small parts together and easy to find in a parts bin.
• Fits LightRail 3.0, 3.5, and 4.0 — covers the common rail models that use this stop style.

Who Should Use this Switch Stop Kit

This kit fits owners of a LightRail 3.0, 3.5, or 4.0 system whose switch stops have gone missing, cracked, or worn down to the point the mover no longer reverses cleanly at the end of its rail.

How Switch Stops Work on a LightRail System

Switch stops sit on the rail and trigger the mover's internal switch to reverse direction, so when a stop is missing or loose, the carriage can overrun the end of the rail or stop inconsistently instead of cycling back and forth as intended.

Frequently Asked Questions

Which LightRail models does this kit fit?

It fits LightRail 3.0, 3.5, and 4.0 systems. Those models share the same switch stop style, so one kit covers all three.

How many switch stops come in one kit?

It includes 3 pairs, for a total of 6 individual stops. That's enough to replace stops at both ends of a rail with spares left over.

Does the kit include screws and nuts for mounting?

Yes, 6 thumb screws and 6 slide nuts are included. Thumb screws hand-tighten without needing separate tools.

How is the kit packaged?

It ships in a compact 4-inch by 4-inch ziplock bag. That size keeps the small parts together and easy to find in a parts bin.

Can I use this kit if only one stop is missing?

Yes, the extra stops in the kit can be kept as spares for future replacements. There's no need to use all 6 at once if only one or two are actually missing or worn.
