LF40 switches offer pressure or vacuum sensors. It is provided with a snap action switching for higher current capacity, SPDT contact form and switch deadbands (also referred to as mechanical differential or hysteresis). Miniature size and low cost make the LF40 ideal for OEM applications. LF40 switches utilize high-quality miniature snap-action switches. The switches are diaphragm operated. Diaphragm material can be selected for the operating medium, temperature range and other parameters. During the development of a specification, actuation point can be adjusted by the designer. In production, factory setting is required.
