If your RV or fifth wheel stabilizer jack switch has failed or corroded, the FBULWSEC 387874 offers a ready-to-install replacement built to withstand outdoor conditions. Engineered to fit Lippert high-speed power stabilizer jacks and to replace part numbers like LC298707, LC198641, and LC363284, this switch arrives with pre-terminated wires and metal contacts for straightforward connection to your RV wiring harness. The IP66 waterproof rating and improved surface treatment increase durability in wet, dusty, or roadside environments.

How does this switch fit my Lippert high-speed stabilizer jack?

The 387874 is designed to match mounting and electrical characteristics of common Lippert high-speed jack switches so you can swap it into the rear landing gear leg without major modifications. It replaces the motor control switch in compatible models and keeps the same extend/retract control layout for intuitive use.

• Direct fit for many Lippert high-speed stabilizer jack assemblies
• Compatible replacement for LC298707, LC198641, LC363284 and similar part numbers
• Pre-wired harness with metal contacts for crimp-and-plug connection

What weather protection and durability does it provide?

This switch uses an IP66-rated sealed design and enhanced surface treatment to protect internal contacts from dust, dirt, and splashing water. That level of protection extends service life when the switch is exposed to rain, road spray, or dusty campsites.

• IP66-rated: dust-tight and protected against powerful water jets
• Sealed housing and corrosion-resistant contacts for outdoor use
• Clear EXTEND/RETRACT markings prevent confusion during setup

How simple is installation and electrical connection?

Installation is straightforward for anyone comfortable with basic RV electrical work: the switch comes with wires exiting the housing and metal contacts that you crimp onto your trailer's existing harness. No soldering is required—just match functions, crimp the contacts, and plug into the jack circuit.

• Pre-terminated wires and metal crimp contacts reduce install time
• Identified switch positions for easy wiring and testing
• Works with common RV jack wiring conventions—follow vehicle wiring diagram

What functionality should I expect during operation?

The switch provides motor control for extending and retracting stabilizer jacks so you can level and stabilize a trailer or fifth wheel. It’s intended as a control interface only—pair it with the correct motor and jack assembly for full operation.

• Two-position control clearly labeled EXTEND and RETRACT
• Designed for responsive control of high-speed stabilizer jacks
• Durable contacts help ensure consistent operation in outdoor conditions

Who this is for: RV owners, RV service technicians, and DIYers who need a reliable, weatherproof replacement switch for Lippert-compatible high-speed stabilizer jacks. If you want an OEM-style swap with clear labeling, pre-wired connections, and enhanced protection against dust and water, the FBULWSEC 387874 provides a durable, install-ready option to restore stabilizer jack control on trailers and fifth wheels.
