PS6000 | Pressure Switch, 9575 PSI Max 3/8 in M, Activates 362.5 PSI

PS6000 Pressure Switch — 362.5 PSI Activation | 9,575 PSI Max | 3/8″ Male

The AR PS6000 Pressure Switch is a heavy-duty, precision-engineered control and safety component designed for automated pump control and system protection in high-pressure applications. With a calibrated activation point of 362.5 PSI and a maximum operating pressure of 9,575 PSI, this switch ensures accurate pressure monitoring, consistent switching behavior, and reliable protection for pumps and connected equipment.

Overview

The PS6000 is built for high-pressure cleaning systems, hydraulic circuits, and industrial machinery that require dependable pressure regulation, automated start/stop functionality, and over-pressure protection. Featuring a durable 3/8″ male threaded connection, it integrates easily into professional equipment and supports long-term, continuous-duty operation.

How It Works

The switch uses a diaphragm-actuated mechanism:

• Rising pressure pushes against a reinforced diaphragm.
• At 362.5 PSI activation pressure, the diaphragm compresses an internal calibrated spring.
• This triggers the microswitch to open or close the circuit, depending on wiring configuration.
• The switch can start or stop pumps, activate shutdown protocols, or signal control modules.
• As pressure drops below the reset threshold, the switch returns to its default state.

This automatic cycling stabilizes system pressure, reduces pump idle time, limits heat buildup, and minimizes wear on motors, seals, and fittings.

Construction & Engineering

• Durable Metals: Built from corrosion-resistant brass or stainless steel for harsh environments.
• Reinforced Diaphragm: Designed for high cycle counts and long-term elasticity.
• Calibrated Spring Assembly: Factory-set for consistent activation without drift.
• Protected Electrical Housing: Sealed to prevent moisture, dust, and chemical contamination.
• Compact Footprint: Fits easily into enclosed or tight installation spaces.
• Standard 3/8″ Male Thread: Ensures secure and leak-free installation in compatible systems.
