Galley Maid MR Pressure On-Off Switch — Genuine Replacement for MR-Series Water Pump Systems
The Galley Maid MR Pressure On-Off Switch is the OEM replacement pressure control switch designed specifically for use with Galley Maid MR-Series pump units. It automatically signals the pump motor to start when system pressure drops to the cut-in threshold and shuts it off once the set cut-off pressure is reached — giving you consistent, hands-free water pressure management without manual intervention. Whether you're dealing with a pump that runs continuously and won't shut off, or one that fails to start when pressure drops, this switch is almost always the component at the heart of the problem.
What makes this switch worth having on hand is its straightforward design and direct compatibility with the MR pump family. A manual lever on the switch body allows you to manually restart the pump after a dry-run low-pressure shutoff event — an important safety feature that prevents motor and stator damage when the water supply runs out. Replacing the pressure switch is one of the most common and cost-effective repairs in any pump-driven water pressure system, and having a genuine Galley Maid part ensures the fit, function, and reliability that aftermarket alternatives often can't match.

Frequently Asked Questions
Q: How do I know if the MR Pressure On-Off Switch is the part causing my pump to run continuously?
If your Galley Maid MR-series pump runs and never shuts off even after pressure is built in the system, and the motor itself appears to be working normally, the pressure switch is typically the first component to suspect. The switch may have failed in the closed position, preventing it from signaling the motor to stop.
Q: What is the manual lever on the pressure switch used for?
The manual lever is a restart mechanism. When the pump runs dry and system pressure drops below the safe cut-in threshold, the switch trips as a protective measure and must be manually reset by lifting the lever before the pump will run again. This protects the stator and motor from damage caused by dry running.
Q: Can this switch be used with Galley Maid pumps running at 12V, 24V, or 32V?
Yes — the MR Pressure On-Off Switch is a mechanical, pressure-actuated component rather than a voltage-specific electronic part. It is compatible across the MR-Series pump lineup regardless of the DC voltage rating of the motor (12V, 24V, or 32V), though you should always verify compatibility with your specific pump model before ordering.
Q: Is this switch compatible with non-marine pump installations?
Galley Maid MR-Series pumps and their associated parts — including this pressure switch — are frequently used in industrial, commercial, and non-marine fluid systems due to their heavy-duty construction. If your system uses a Galley Maid MR-Series pump, this switch is the correct replacement regardless of the installation environment.
Q: How difficult is it to replace the MR pressure switch myself?
Switch replacement is considered a straightforward repair for anyone comfortable with basic plumbing and electrical work. The process typically involves depressurizing the system, disconnecting the wiring at the switch terminals, unthreading the switch from the pump body or pressure line fitting, and threading in the replacement. Always cut power to the pump before beginning any service work.
