Saginomiya Pressure Switch  normally used in fire pumps and sprinkler risers to monitor and control system pressure. It also acts  as a pressure sensing and signaling device, when system pressure rise or drop beyond the set value, it activates an electrical contact to start, stop, or alarm connected equipment.



 

Application Area	Function Description
Fire Pump Control Panel	Detects discharge pressure - starts main or jockey pump when pressure drops, and stops when restored.
Sprinkler System	Monitors water pressure in the riser - triggers alarm or signal when water flow or pressure change occurs.
Deluge or Pre-action System	Detects pilot line pressure drop to activate deluge valve or open control circuit

 

• Reliable - Japanese-made industrial standard
• Compact size - Easy to fit inside control boxes or near valve manifolds
• Corrosion-resistant materials - suitable for long-term service in pump rooms.
• Single SPDT contact output for control/alarm circuits.
