LF40-02P switch utilizes two high-quality miniature snap-action switches with higher current capacity, SPST or SPDT contact form and switch deadbands (also referred to as mechanical differntial or hysteresis). The switch is diaphragm operated. Diaphragm material can be selected according to the operating medium, temperature range and other parameters.

LF40-02P pressure switch can control the system pressure in a steady range by adjusting the operating pressure and the differential pressure of the two snap-action switches.
