What This Does

The hydraulic pressure switch is the safety sensor that monitors hydraulic system pressure — signals the leveling or slide-out control system when target pressure is reached, when pressure is lost, or when pressure exceeds safe operating limits. Meaningful failure symptoms suggesting switch replacement:

• Leveling system doesn't stop at proper pressure — continues running past target
• System doesn't confirm pressure — reports fault or won't complete leveling cycle
• Slide-out doesn't retract fully — pressure-confirmed stop position missing
• Erratic system operation tied to pressure feedback

⚠️ Switch Only — Sensor Replacement

Important buyer note: this listing includes the switch only. Other components in the hydraulic system (pumps, cylinders, fittings, hoses) are sold separately.
