Whale Inline Pressure Switch The Whale Inline Pressure Switch switches the pump on or off by detecting the change in pressure in the water system. It is the ideal water pressure switch specifically designed for your caravan, motorhome, or campervan.
Fitted in-line, the Whale Pressure Switch provides a simple and convenient way of creating a pressure system with an electric pump that does not have its own switch. The Pressure Switch is normally fitted close to the pump on discharge side (before any in-line Y piece). The Pressure Switch detects the opening and closing of any tap in the system. An in-line filter is recommeded on the inlet side to prevent dirt from entering the pump or switch.

Features:
- Detects change in water pressure
- Fitted inline
- Normally fitted close to the pump, on the discharge side
