P Sereis Simple SPDT Pressure Switch

　 　
• Pressure switched can be used not only in fluoride refrigeration, but also in the air and liquid.
• Allowed medium temperature: -45°C to +120°C.
• Renovated micro-switch structure ensures the reliable switch function.
• Flexible mounting plate suits various kinds of application.
• Single Pressure Controls divide two types: High pressure and Low pressure, they are mounted
on low-pressure or high-pressure end of the compressor to control the exhaust and inspiration
pressure of compressor.
