# TLNLMY 30–50 PSI Well Pump Pressure Switch

TLNLMY’s well pump pressure switch is listed with a 30–50 PSI adjustable operating range and a 1/4-inch female NPT connection. It is intended to switch a pump on and off according to water pressure, rather than boost pressure itself.

## At a glance

- The listing states a 30 PSI pump-on point and a 50 PSI pump-off point.
- Pressure control is intended to automate pump starting and stopping as line pressure changes.
- The 1/4-inch female NPT port is listed for jet, submersible and reciprocating pumps.

## Pros

- A defined 30/50 PSI switching setup gives buyers a clear starting point for systems requiring those thresholds.
- The listing identifies a standardised connection type and several pump categories for fitment consideration.

## Cons

- This is a control switch, not a pressure booster, so it cannot raise water pressure by itself.

## Before you buy

- Listing details conflict on voltage: the electrical specification gives 230 Volts, while the description lists 110V/230V. The product description also calls the pressure setting range 30-50 PSI while the feature text presents 30 PSI on and 50 PSI off. Confirm the correct electrical supply and switching settings for the selected item before installation. The stated prevention of dry runs is a manufacturer claim, not established protection performance.

## In the box

- Other (Included): The included-components field is unspecified, while the product description explicitly lists one well pump pressure switch. Check the selected listing for the package contents.

## A good fit for

- Well-pump owners seeking an on-off pressure switch for a system set around 30/50 PSI.
- Buyers whose pump installation accepts a 1/4-inch female NPT connection and matches the stated electrical requirements.

## Less suited to

- Anyone needing a device that boosts water pressure.
- Installations requiring a confirmed voltage or connection specification that differs from the listing.

## Customer feedback

The supplied evidence contains only a single aggregate rating and no written customer feedback. That small sample cannot establish how reliably the switch performs or whether it suits a particular pump installation.

## Frequently asked questions

### What pressure settings does the listing give?
It lists a 30–50 PSI range and says the pump turns on at 30 PSI and off at 50 PSI. Confirm those settings for the supplied switch, as the listing describes them in more than one way.
### What voltage does it use?
The electrical specification says 230 Volts, but the description states 110V/230V. Check the applicable voltage before choosing or wiring it.
### Will this switch increase water pressure?
No. The product description says it controls a pump’s automatic power-on and power-off functions and does not provide a boost function.
### Which pumps are listed as compatible?
The listing names jet pumps, submersible pumps and reciprocating pumps. Check that the 1/4-inch female NPT port and electrical requirements suit your particular setup.
