LF37 diaphragm pressure switch is available for various sumps, effluent, and sewage application to control the liquid level. Various switch settings are available for to turn-on or turn-off the pump. The diaphragm pressure sensing design make it more reliable than traditional float ball mechanism.

LF40-01 can be used togethr with an air button (also called as Actuator ) for remote control purpose. It is widely used in food waste disposers, pumps for swimming pools and spas, hot tubs, sanitary equipments, out door machines,medical equipments ect. As remote control switch, it i small enough to fix in the control box of the engine. Used as a remote control the air switch has two actions:

1. Momentary action: when the air button is pushed, the air switch is actuated. When the air button is released, the air switch will also be released. This is the way the basic pressure switches are working.
2. Alternate action (also referred to as latching or bistable): the first pushing on air button actuates the air switch, and the air switch keep acuating when air button is released. A second push on the air button will release the air switch.

LFS-01 pressure switch is applied to detection of negative pressure, widely used in electrical appliance such as the vacuum cleaner, paking etc. It provides solder pin connections and is especially designed for mounting on "Printed Circuit boards".

LFS-02 pressure switch is designed as an economical interface between pressure systems and Printed Circuit Boards. This switch can be used as a gauge or differential pressure switch with almost no hysteresis. Features of this switch include a body design that allows the pressure ports to be rotated, various terminal styles including wire leads. Strong and reliable, LFS-02 is a popular choice for many manufacturers.

LF25 pressure switch is to control the pressure of application with higher current catacity. It is widely used in stream cleaner, stream iron and othe pressure control system. It provides SPST or SPDT contact form and switch deadband (also referred to as mechanical differential or hysteresis).

LF25 switch utilize high-quality miniature snap-action switches. The switch is diaphragm operated. Diaphragm material can be selected for the opering medium, temperature range and other parmeters. During the development of a specification, acuation point can be adjusted by the designer, in production, factory setting is required.

The LF20 pressure switch is specifically designed to stand up to extended duty applications. This switch is factory set but capable of field adjustment. It features different diaphragms for compatibility with a wide variety of fluids, and various terminations including a Metri-Pack connector that forms a tight seal when connected. Among the outstanding design benefits are its durable construction, compact size, and enhanced set point integrity.

It can be widely used for pool and spa, anti-skid braking systems, water pump systems, and dental air compressors, heavy construction, off road applications and other pressure control systems.
