The KOBOLD KPH Series compact pressure switch is a highly reliable, small footprint pressure switch ideal for OEM installations. Its long cycle life and rugged mechanical design ensure OEMs that it will provide their customer with reliable service during the life of their product. The Model KPH-8000 compact pressure switch may be used with gases or liquids, such as air, gas, lubricating oil, light fuel or any one of many other compatible industrial media, while the Model KPH-8200 is designed for use with liquids only. The KPH Series compact pressure switch’s single-pole double-throw (SPDT) switch has mechanical reliability typically found only in reed switches. Unlike reed switches, however, the KPH Series compact pressure switch is capable of switching AC loads of up to 5A at 220V. Rugged, compact and reliable, the KOBOLD KPH Series is the perfect OEM pressure switch for your pressure switching applications.
