PSW tank pressure sensing electrical switches are intended for in-line mounting as close to the hydropneumatic product water tank as possible. Its purpose is to turn off the booster pump when the tank is full. The normally closed switch can be factory pre-set at various shut-off pressures. The PSW, when used with a typical under-counter RO system, enables the hydraulic shut-off valve to open and close very reliably and positively.
