Pressure Switch

A pressure switch is a practical and reliable sensor used to monitor and maintain water pipe pressure in pumps, water systems, tanks, and piping installations. It helps detect pressure changes and automatically triggers connected equipment when the pressure reaches a preset pressure level.

We supply pressure switches suitable for industrial, commercial, and general water pressure control applications in Singapore.


What Is a Pressure Switch?

A pressure switch is a control device that responds to pressure in a pipe or system. When the water pressure rises or drops to a preset value, the pressure switch opens or closes an electrical contact.

This allows the switch to control pumps, alarms, indicators, or other equipment used to maintain safe and stable water pressure.

Common Applications

  • Water pump pressure control
  • Water pipe pressure monitoring
  • Booster pump systems
  • Water tank pressure systems
  • Industrial water piping
  • Building maintenance systems
  • Automatic pump start and stop control
  • Pressure safety monitoring

How It Helps Maintain Water Pipe Pressure

In a water pipe system, pressure may change due to pump operation, water usage, leakage, or system demand. A pressure switch helps monitor these changes and sends an electrical signal when the pressure reaches the preset value.

For example, when the pipe pressure drops below a certain level, the pressure switch can activate a pump. When the pressure reaches the desired level, the switch can stop the pump. This helps maintain consistent water pressure and protects the system from unnecessary pump operation.

Key Features

  • Reliable pressure sensing for water pipe systems
  • Suitable for pump control and pressure monitoring
  • Helps maintain stable water pressure
  • Can be used for automatic start and stop control
  • Compact and easy to install
  • Suitable for commercial and industrial applications
  • Available in different pressure ranges
  • Durable design for long-term operation

Why Use a Pressure Switch?

A pressure switch is useful when you need a simple and effective way to control equipment based on water pressure. It reduces the need for manual monitoring and helps protect pumps and pipe systems from pressure-related problems.

It is commonly used in water supply systems, pump rooms, industrial equipment, and building maintenance applications.
