Pressure switch with SPDT contact
- Series of pressure switches for control applications and supervision in different technological systems (fi re fi ghting units, building machineries, systems for water treatment, etc)
- The pressure switch works mechanically per action of the pressure in the system and it doesn't need any additional electrical power supply
- SPDT contact (single pole double throw COM.-N.O.-N.C.)
- Electrical terminals: 3 rising clamp terminals (COM. + N.O. + N.C.)
- NBR rubber membrane with textile insert
- ¼" F hydraulic connection made of galvanized steel
- Protection degree IP44
- Max ambient temperature 55°C
- Tear resistant cable clamps
