STERWINS POC-3 PRESSURE SWITCH

Intended Use

The Sterwins POC-3 pressure switch is primarily designed for domestic water supply and irrigation systems. It is a mechanical controller that automatically starts and stops a water pump when a tap or valve in the system is opened or closed. It is not intended for use by children or persons with reduced physical, mental, or sensory capabilities, nor for commercial, trade, or industrial applications.

The device can control the on/off operation of multiple pumps. Its function is based on pressure changes in the plumbing system. When the pressure reaches a pre-set upper limit, the switch cuts off power and stops the pump. When the pressure reaches a pre-set lower limit, the switch reconnects power and starts the pump, thus completing the automatic control process.
