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