Water Pressure Switch – 3-Terminal Replacement Assembly

This mechanical water pressure switch is a replacement component for compatible water-system monitoring and control applications. A pressure-actuated mechanism changes the electrical contact state, allowing a connected control system to detect a pressure condition.

The switch assembly features a round housing, three electrical blade terminals, and a metal mounting bracket. It is intended for replacing an existing switch with matching mechanical connections, electrical characteristics, and operating requirements.

Pressure switches may be used as part of equipment monitoring or protection circuits. The specific function depends on the machine's wiring and control system.

Important: This component is not a universal replacement. Confirm the electrical contact arrangement, pressure operating range, and physical dimensions of your existing switch before ordering.

Key Features

• Pressure-Actuated Switching: Changes electrical contact state in response to a pressure condition.
• Three Electrical Terminals: Features three blade-style terminals for connection to a compatible electrical circuit.
• Mechanical Operation: Uses a physical switching mechanism rather than a continuous electronic pressure-reading display.
• Mounting Bracket: Includes a metal bracket for installation in a compatible equipment assembly.
• Replacement Application: Intended for replacing a matching pressure switch in compatible water-system control equipment.

Specification Note: The switch's electrical ratings, pressure actuation setting, and exact terminal assignments have not been confirmed. Compare the replacement with the original component before installation.

Compatibility

This pressure switch is intended for equipment using a matching mechanical pressure-switch assembly. Compatibility depends on the original switch's electrical characteristics, pressure requirements, mounting arrangement, and physical connections.

Before ordering, compare the replacement with your existing component, including:

• Manufacturer and model number, if available
• Electrical terminal arrangement and contact functions
• Voltage and current ratings
• Pressure operating range and switching threshold
• Pressure connection and mounting dimensions
• Physical orientation and available installation space

Important: Having three terminals does not guarantee that two pressure switches are interchangeable. The contact arrangement and switching behavior must match the requirements of the connected equipment.

Installation & Safety

• Disconnect equipment from electrical power before servicing.
• Relieve system pressure and isolate water connections as required by the equipment manufacturer's procedures.
• Confirm that the replacement switch matches the original component's operating specifications.
• Identify and verify each electrical terminal before connecting wiring.
• Mount the switch securely using the appropriate hardware and installation orientation.
• Do not modify the pressure actuation setting without the correct manufacturer instructions and testing equipment.
• Inspect the installation for loose electrical connections and water leaks.
• Verify correct switching operation and any associated protection functions before returning equipment to service.

Safety Note: Pressure switches may form part of an equipment protection circuit. Never bypass or improperly rewire a protection device to keep a machine operating.
