AL695 Mini Pressure Switch | 3/8 in Male, Reliable Pump Control

AL695 Mini Pressure Switch | 3/8 in Male, Reliable Pump Control

The AR AL695 mini pressure switch is a compact, high-precision control component engineered by
Annovi Reverberi to provide automatic, reliable pressure regulation in high-pressure cleaning systems. Designed
with a 3/8″ male threaded connection, this switch integrates seamlessly into pressure washer
pumps, manifolds, or system outlets, ensuring smooth and consistent pump control in both professional and
residential environments.

How the AL695 Regulates Pressure

The AL695 continuously monitors system pressure and automatically controls the pump’s start/stop cycle:

• When pressure in the line drops below a preset threshold, the switch closes the circuit and starts the pump.
• When pressure reaches the upper limit, the switch opens the circuit and shuts the pump off.

This automatic regulation prevents over-pressurization, minimizes wear on mechanical components, conserves
energy, and maintains stable system performance without manual intervention. The 3/8″ male thread provides
a strong, leak-resistant fit so the switch can manage high operating pressures with accuracy and stability.

Construction & Internal Design

Constructed from solid brass, the AL695 offers excellent corrosion resistance and structural
strength. Brass tolerates temperature variation, vibration, and chemical exposure without deformation or thread
damage, making it ideal for high-pressure fittings. Precision-machined threads deliver a secure seal, while the
fixed, non-rotating body keeps alignment stable during long-term use.

Internally, a responsive diaphragm couples to an electrical contact assembly designed for consistent operation
across thousands of pressure cycles. The diaphragm senses even small fluctuations in pressure, engaging the
contacts with precision to maintain balanced water flow and consistent spray patterns at the nozzle.

Sealed Housing & Compact Form Factor

The AL695’s sealed housing protects internal components from moisture, detergents, and debris, reducing
maintenance needs and extending service life—especially important for equipment used outdoors or in humid wash
bays. Its compact, lightweight form factor allows easy installation in tight spaces on portable units, mobile
wash rigs, and fixed wash stations where efficient use of space is critical.

Because the switch is tuned for high sensitivity, the pump starts and stops smoothly, preventing sudden spikes or
drops in pressure that could affect nozzle performance or strain downstream equipment.

Installation & Integration

Each AL695 is manufactured and calibrated under Annovi Reverberi’s strict quality standards to ensure accurate
switching pressure and repeatable reliability. Installation is straightforward:

• Thread the 3/8″ male fitting into a clean, compatible system port.
• Snug to the recommended torque to achieve a watertight seal without over-tightening.
• Verify proper cycling by observing pump start/stop behavior under normal operating conditions.

Once installed, the switch operates automatically and typically requires only occasional inspection to confirm
cleanliness and sound electrical connections.

Applications & Benefits

The AL695 is compatible with a wide range of Annovi Reverberi pumps and other systems that utilize
3/8″-threaded fittings. Typical uses include:

• Car wash and detailing systems.
• Commercial cleaning equipment and mobile wash rigs.
• Agricultural sprayers and farm wash stations.
• Industrial and municipal wash bays.

By preventing dry running and limiting mechanical stress on seals and valves, the switch helps extend pump life,
reduces mechanical failures, and promotes efficient energy use while maintaining consistent cleaning performance.
