The Multiquip 29879 Ballast Cover Snap Fit Switch is a genuine OEM replacement designed for LT12 and SLT12 series towable light towers. Sourced directly from Multiquip, this part matches the original component specification used on LT12, LT12D, LT12DAB, LT12D50B, LT12D50SA, LT12P, and SLT12D light towers. When the cover or its integrated switch fails, the ballast system can lose protection and trigger electrical faults — making a fast, accurate replacement critical to keeping your tower operational on site.
Key Features
- Genuine OEM Electrical Integrity — Manufactured to the original switch contact and housing spec, ensuring the ballast circuit receives the correct signal without improvised workarounds.
- Snap-Fit Installation — Designed with the original snap-fit retention system, so the cover seats and secures exactly as the factory unit did — no drilling, tapping, or hardware modification needed.
- Broad LT12 Series Compatibility — Confirmed fitment across LT12, LT12D, LT12DAB, LT12D50B, LT12D50SA, LT12P, and SLT12D Multiquip towable light tower models.
- Ballast System Protection — The cover shields internal ballast components from dust, moisture, and physical contact; the integrated switch ensures the ballast engages only when the cover is properly seated.
- Electrical Safety Function — The snap fit switch acts as an interlock, preventing ballast energization when the cover is open or unseated — a critical safeguard for operators working around high-voltage lighting circuits.
The ballast cover on a towable light tower does more than protect internal components — its integrated snap fit switch functions as a safety interlock for the ballast circuit. When the cover is properly seated, the switch signals the system that it is safe to energize the ballast and strike the lamp. If the cover is cracked, missing, or the switch fails to make contact, the tower may refuse to light or cycle repeatedly without igniting. Replacing a worn or damaged Multiquip 29879 restores both the physical protection and the correct switching function to get your light tower back in service.
