## Summary description

Electric pressure switch Omnigena HWA-18-Ż with 1/4" female connection and 230V supply. Designed to control pumps by switching electrical power based on system pressure. Suitable for domestic and light commercial water systems, pressure tanks and pump automation where automatic on/off control at defined pressure thresholds is required.

## Long description

The Omnigena HWA-18-Ż pressure switch with a 1/4" female connection and 230V supply is designed to control electrical pumps by opening and closing the power circuit according to system pressure. It monitors pressure in water systems and initiates pump start or stop at defined pressure thresholds. The compact construction and standard 1/4" thread make it compatible with pressure tanks, pump housings and plumbing installations used in domestic and light commercial water systems.
Advantages
This pressure switch provides reliable automatic pump control with simple mechanical adjustment of cut-in and cut-out pressure points. The 230V supply makes it directly compatible with common household and small commercial electrical networks. The 1/4" female connection enables straightforward mounting to existing fittings or manifolds, and the robust housing protects internal components in typical indoor and sheltered outdoor installations.
Suitable for
Automatic control of domestic water pumps
Pressure vessels and expansion tanks in household systems
Small commercial water supply and irrigation systems

Key specifications
Supply voltage: 230 V AC
Electrical connection type: standard terminals for single-phase pump control

How to use
Install the pressure switch on a pressure port or manifold with the 1/4" female thread, ensuring appropriate sealing to prevent leaks. Connect the electrical terminals to the pump and mains following local electrical codes and safety regulations; switch off power before wiring. Adjust the cut-in and cut-out pressure settings if applicable per the manufacturer's instructions so that the pump starts and stops at the desired pressures. After installation, test the system by allowing pressure to fall and rise to verify correct switching and secure electrical connections.
Usage recommendations
Use the pressure switch in environments protected from heavy moisture and freezing temperatures; if installed outdoors, provide a suitable enclosure. Regularly inspect electrical connections and hydraulic seals, and perform functional checks after maintenance or prolonged inactivity to ensure continued reliable pump control.
