EQ Systems El Pac Rotary Switch #7779 | Switch Only | El Pac 1 & 2 Systems

Replace the rotary switch inside your El Pac electric jack switchgear with the EQ Systems El Pac Rotary Switch (Part 7779). The El Pac is an electric gearbox that bolts to an existing manual trailer jack and motorizes it. Available at The RV Surplus.

Switch only — does NOT include the switch box or wiring harness. For the complete switchgear, order Part 7817.

⭐ El Pac Compatibility

• El Pac 1: lifts up to 5,000 lbs. Fits Bulldog, Fulton and Ram single-speed jacklegs and 2-speed Bulldog jacklegs
• El Pac 2: lifts up to 6,500 lbs. Fits Binkley 2-speed jacklegs only

⭐ Check Which Style You Have BEFORE You Start

Look at the switch housing inside the switch box:

• ✅ Gold-colored housing = newer style — 7779 is a direct replacement, none of the extra work below
• ⚠️ Silver-colored housing = older style — needs the wiring adaptation described below

⭐ Older (Silver) Housing Wiring Steps

• New switch lugs only take wire terminals on one side, so the two outer terminals (A1 and A2) are attached and bent back over the attaching screw
• The two center terminals (B1 and B3) are bent away from the screw
• Black heat-shrink tubing is included for the white wires, to keep them off the other terminals
• A larger piece of red heat-shrink goes over the red wire once the screw is tight, covering the whole terminal including the screw
• Terminals are labelled and sit in the same places as the original
