LF25 Pressure Switch

Brand: Mamco

The LF25 pressure switch is used to control the pressure of applications with higher current capacity. It’s widely used in steam cleaners, steam irons and other pressure control systems. 
It provides SPST or SPDT contact form and switch deadband (also referred to as mechanical differential or hysteresis). 

The LF25 utilizes high quality miniature snap action switches. The switch is a diaphragm operated. Diaphragm material can be selected for the operating medium, temperature range and other parameters. 

During the development of a specification, actuation points can be adjusted by the designer but once the switch enters production, a factory setting is required.
Features
  • Multiple diaphragm options makes it compatible with many mediums
  • Externally mounted snap action switch has current capacity up to 25 amps
  • Durable, high-performance switch popular for applications where hysteresis is required
